Ask Slashdot: Best Use For an Old Smartphone?
zaba writes "The original iPhone was a dream come true for me. Phone, camera, mp3 player and data all in one device. It had more cpu and memory than my first computer! Several generations of smartphones later, my wife and I have some random smartphones (some iPhone, some Android) lying around. Between privacy concerns, bad batteries, etc. these phones are not worthy of donation. So, I ask you, Slashdot readers, have you done anything fun with an old smartphone? Any suggestions/ideas?"
For science, of course.
"To those who are overly cautious, everything is impossible. "
The batteries aren't as hard to replace as some non-techies make you believe. Buy the parts from chinese retailers, do the work yourself and the phone will perform like when it was new. There are a lot of people with worse phones, who would appreciate even an old smartphone.
Actually, for real. Has anyone considered networking a couple hundred old iPhones or Android phones together to form some sort of beowulf cluster of them?
Phone, camera, mp3 player and data all in one device
Older Symbian s60 devices did the same for a much lower price and IIRC better battery life
It wasnt a dream come true, it was a feature phone dressed up as a smartphone
Plug it in and use VNC to a separate session to make it a mini-head for monitoring things like email, tweets, system sensors, etc. For example, what I did with my tablet.
Can You Say Linux? I Knew That You Could.
For Android phones, use it as a Web/FTP/DNLA/DNS/Email/Proxy server.
With a couple of phones that have user-facing cameras, you could set up a sweet touchscreen video intercom at your frontdoor. If you're worried about them being thieved, you could conceal all but the camera lense and make it a one-way experience only.
For that matter you could use them as wireless CCTV security and potentially check in on them from home, the office, while on holiday.
Donate the phone to the elderly http://www.securethecall.org/. Oh wait, this is slashdot. Root the phone and then donate it.
I use old phones over wifi to control my XBMC media boxes. When I build my new house in a few years, I'll probably incorporate them into home automation since I'll have around 10 lying around. Most phones in airplane mode with wifi will last at least a week, and it lets me have chargers around the house to keep them (or my current phone) plugged in most of the time.
... is vaguely mind-boggling to me.
I must be getting old.
The correlation between ignorance of statistics and using "correlation is not causation" as an argument is close to 1.
I believe I bought my iPhone 3G for $300 on launch day and I sold it about 3.5 years later to a friend for $125, which was well under the asking prices at that time, most of which were around $150-175 if memory serves. I was shocked to see that it had held its value so well, despite being two generations outdated at that point (and feeling like it too).
The scene might be a bit different these days, now that Apple has started offering older models for lower prices, but considering your phone can be purchased without needing to commit to a contract, that alone makes it more valuable than you may realize.
mp3 player, of course a good rom would permit FLAC and other formats... however you would probably need a good capacity SD card (if the cell supports it) ...just keep it in airplane mode to improve battery life.
Plug the phone into a wall outlet and install one of the numerous free Android apps that turns the phone into a wi-fi IP video camera. Mount it on your front porch and see who stops by when you're not home. Integrate the camera into an external Zoneminder server if you want motion detection, alarms, and recording.
Mount it near your toilet for easy access to Angry Birds or whatever when in the toilet, or set up a small speaker set in your shower room and use the smartphone to play music from online streams over WLAN or similar.
Build a cool ass steam punk enclosure for it. Make it a table top phone with a handset using a mic and headphones (hide them inside the ear and mouth piece). Keep the display but root it and get some brass typeset graphics for the number keys, etc.
If it can do Skype or video chat try that too.
Make the enclosure big and brass with lots of adjustable levers for positioning it (3 arms would do).
OR
Make a Jukebox out of it and enclose it in something with cool speakers.
Maybe even both.

Call forwarding isn't a phone feature, it's a carrier feature.
Are you unsure if you can completely wipe the phone?
Anyways, put it on craigslist. Or ask around. I'm sure someone will be willing to take them. I use Android devices as scoring devices for quiz meets, so if someone wanted to give me a pile of Android phones, I'd be happy. Or if someone wants to get into development, having a range of phones is always helpful.

I always keep my previous Android as not only an emergency spare, but use it in a dock in the bedroom as an alarm clock and weather station.
The only thing annoying is that you can't use NTP with it, unless you are rooted... so since there is no cell connection, time will drift.

Perhaps, the most fun use of an old smart phone is the mobile phone throwing contest
Do you have any plans to do mobile development? If so save them for debugging and testing. You may want to leave old operating systems on them for this purpose.
If you have no interest in mobile development do you have someone among your family and friends who does? Give it to them for debugging and testing.
Give it to one of the Open Source mobile distribution developers! For example: Replicant, SHR, Debian:

Didn't they just do that with 500,000 Android phones in China?

Yeah, but those of us who don't have a life can use half-dead Android phones as Arduino controllers.
Or we could use them with AndroUAV to control our own drones.

If it's in good shape and still works, you can still get a decent price for them.
It's still quite a usable device.

If you're thinking of making one giant LCD display out of them (to connect to your computer), it's a LOT harder than you think. Many people that start such a project overlook the bandwidth requirements of what-ever computer is generating the content for all the displays. Even physical links (DVI, etc) can't handle a whole lot more than an expensive computer monitor without needing a second cable to handle the additional bandwidth.
I believe this is what you're looking for:

I'd use them as a device to stream music somewhere in the house. A bathroom stereo system, maybe put one out in the shed, with the added bonus of it having wifi ability to connect to the net if required.
... wait, what?
I'm pretty sure all that counts as more of a life than going to a bar and getting wasted on the weekends. Really. Don't put yourself down just because you do something with your life.

I just bought a new nokia C2-01 as my primary cellphone! and now THIS?!
Hej! Nasi tu byli!
My old S60 series Nokia - it has offline maps, with driving instructions (and voice guidance) and a working GPS. I got a car-window mount and a recharger for that (cost about â 10) and now it serves as a navigator in my car. I connect it via USB every few months to load in the latest map data, but other than that, it now lives in the glove compartment when not in use.
I am using one of my older 7" tablets as a bedside clock at the moment, always synched and accurate

I throw them at the kids on my lawn. But the lil' bastards just keep coming back for more, so I keep the .410 with rock salt loads handy.
The cell phones are rich in rare Chinese vitamins and minerals, and eventually get buried beneath all the beer cans, and other trash. So I am effectively building a rare earth heavy metal mineral mine for my great-great-great-grandchildren.
I am also hoping that some of the kids might port Openwrt to the phones that they pick up.

I would like to put my old Android mobile/tablet into my Car, and use it as a GPS logger. It would charge from the car battery. I would be able to access it from the web if my car where to be stolen, and see where it is, and see who's in my car via a tiny camera. There also would be a camera facing outside front and back (or omni) to catch other events while parked.
So basically, is there an app that turns my old android into a dedicated Car GPS logger + CarCam unit?

Lots of organizations donate old cell phones to the underprivileged. The point is that the telcos are required to accept calls from cellphones dialing 911, regardless of whether they have a plan or not. As long as the old cell phone has a charge and a signal, it provides security to folks who might have (say) a problem with spousal abuse, or...
how does it count more? Its all just doing stuff.
If you're doing it with non-realtime content as a form of public performance art of finite duration, it's fairly straightforward: stream it slowly in advance, with each phone buffering its individual pixel value for each frame along with a timecode, then use the network to just transmit the clock & timecodes and have the phones step through their pre-buffered values on schedule.
It's kind of like an orchestra with a director -- unless they're all spontaneously improvising jazz, they have sheet music in front of them that was given to them (and well-practiced) long before the actual performance. The director isn't communicating the note and duration to each individual musician in realtime -- he's just conveying timing info to keep them all in sync.
I am amused that you say "laptops with much larger screen, keyboard and USB ports are far more cost effective" than using an old Android phone. If he doesn't have said laptop and DOES have said android phone...how exactly is it more cost effective to throw away the phone and buy a laptop?
Got to love the demonisation of the poor. It's much cooler than being racist. SImply change the word "black" for "welfare recipient" in all of your rants and no-one will bat an eyelid.
It's not like we're in the middle of the worst economic crisis for decades, with many people being laid off and needing society to help them get by while they try to be the one person out of the two thousand who applied to actually get the menial, low-paid job that is all that's on offer in the ex-industrial town they had the misfortune to be born in. Heaven forbid anyone would aspire to owning a consumer good which the constant saturation of advertising states is the only way to validate yourself as a person.

If it's worth the $25 a month to you, you can buy a data only plan from Simply Mobile, plug the phone into your 12v line and hide the phone in your car. If your car gets stolen, you'll be able to locate it. That all assumes of course that the phone has GPS.
When the GP said "Intelligent people don't even HAVE a TV" I think it's fair to say "If intelligent people have a TV, they just use it as a monitor, they don't watch 'TV programming'" on it.
If you don't count PBS, and the occasional cable or satellite channel that is worth watching, then there's not much "TV" to watch.
I don't count NetFlix, DVDs, and the like as "TV" since they don't require any kind of "TV tuner."
In the late '70s I knew a family who didn't have TV for religious reasons. But to be fair, without cable they would only had 3 channels - the local ABC, NBC, and CBS affiliates Cable-tv only brought in another 8 or 9 TV stations from cities within about 100 miles.

excuse my rant, but why the EF do you have all this crap? wasn't the first one good enough?
I have a Sony-ericssen almost smart phone from 2007. It still plays my MP3s, movies, makes phone calls, it could do push mail for me (but frankly I don't want to be bothered by email all the time). I deliberately didn't want a camera when I got it and don't feel that I missed a thing.
And I still have it.
And I still use it.
It is still good enough for what I wanted it for.
Perhaps your phone is something more than what I see and that you are admitting. Perhaps your phone is a piece of jewelry to tell the world that you are that special person who is "cool", up to date. Special in that good, hip way?
Sorry, but you should have taken all the money you wasted on that crap and done something to help someone
