RIM Crippling BlackBerry Bluetooth Speed?
Alex King writes " I organized a bounty for the creation of a 'BlackBerry as a modem' solution for Mac OS X earlier this year. The resulting product — Pulse, from Brain Murmurs — allows you to use your BlackBerry as a standard Bluetooth modem. It works great on both Windows and Mac. Current problem: The Pulse solution doesn't run as fast as it used to. Brain Murmurs did a bunch of testing and working with their users and found the problem: RIM has crippled the Bluetooth speeds in recent OS upgrades. Is this a 'mistake' on RIM's side that will be fixed? Or did they do this on purpose for some reason?"
Maybe the author of the blog should have considered asking RIM what the problem is?

There are shills on slashdot. Apparently, I'm one of them.
We here at Slashdot will rationally analyze all the nuances of your question before replying with a well-researched and neutral opinion. You just wait.
Haven't seen an IP over RF provider who didn't start ruthlessly choking off bandwidth to anyone who actually consumes more than a few sips of their 'high speed Internet' products. It is OK if you do a few short bursts now and again, that is the usage model they built their network around. A Blouetooth connection to a laptop implies more than that so once the network operator noticed they had users USING their network they acted quickly to fix the problem.
The crux of the problem is that no RF system that has been deployed has enough bandwidth to supply 'broadbad' like connectivity to very many people at the same time. So the early adopters get it good, tell their friends and watch it all turn to crap. Unless we see microcells on every lamppost we aren't likely to ever solve the problem either. And no amount of marketing promises can change it, you can't repeal the laws of physics.
Cable modems had exactly the same problem of a shared resource quickly becoming overused. The cable industry could solve it by breaking up their originally simplistic network into lots of small segments because they could string FIBER to backhaul all of the neighborhood networks. Unless the wireless companies want to do likewise they are never going to be a player in the broadband game as anything other than a niche product priced high (billed by the bit) enough to limit usage to the available spectrum.

RIM didn't design the cell phone network, dorkwad. RIM the other devices work over the approved and paid for data channels. If you are paying $80/mo for "unlimited data" you better damn well get what the system can handle. And FYI, CDMA and GSM systems use a time division multiplex method so it's not like a cable modem link shared with the neighbourhood; you can't choke the whole system by being a data-hog, at most you can consume your alloted time-slice.
Since the question of this story is rather pointless, I'll go slightly off topic.
One thing that RIM is "crippling" is 911 systems across the nation. My wife and I both have one of those new Blackberry 8100 Pearl smartphones. It's really nice, except for one major flaw. When the phone is locked, pressing the scroll wheel once, rolling it down and pressing it again automatically makes a call to 911 - and there is no way to turn it off. It may seem like with three actions required (press, roll, press), it wouldn't be that easy to accidentally make a call, but my two year old son disagrees. He has made at least ten 911 calls over the last week on mine and my wifes phones combined and a couple of times the calls were triggered when the phone was just sitting in my pocket.
With all of our previous phones, we would lock them and if my son picked them up it would be no big deal. Now, we are forced to either have our phones on us at all time, or put them on the top of the fridge or some other extremely inaccessible place.
I've put a request in to RIM to make it so you can disable that feature in their next software update. Hopefully they listen.
I don't always use unix-like operating systems; but when I do, I prefer FreeBSD.
Dear AlexKing, Instead of accusing RIM of disabling your "bountied" software, why don't you open source it so that we can all look for bugs in the implementation? After all, when the bounty was offered no one told any of the contributors that this would be for a commercial, closed source product, and many of us who contributed to the project are angry and disappointed that it was hijacked for a proprietary, closed project. Open it up!!!
When you use a Blackberry as a GSM modem, the data never (or at least, shouldn't ever) travels over RIM's network. It's not like you're chunking a file into little pieces and attaching it to emails. It's just using the Blackberry's connection to the cellular network to transfer data.
If the cellular company didn't want you doing that, they could certainly ratelimit you, but generally most people using smartphones have an unlimited-data plan, which would let them use a PC Card-style GSM modem or other type of phone to push as many packets as they wanted. The cellular infrastructure is designed to give data service a lower priority than voice calls, and it's all designed with QoS in mind -- this isn't like your neighborhood cable modem setup. I know that T-Mobile doesn't mind if you use full-speed Internet access on your EDGE device; that's included in the $30/mo extra you pay for data access. (I assume if you were really abusive in some way, they might cut you off, but that's not the issue here.)
I think that this guy should send a polite letter to RIM asking what the deal is. I don't get if it's an all-over Blackberry issue, or a PC/Mac one, where PC users can do this modem thing at full speed, and Mac users get a reduced rate. If that's the case, then it's fairly odd. But more likely, I tend to wonder if they didn't just drop the rate on the BT connection because they never figured that anybody would be doing anything with it other than using BT headsets and syncing data with their desktop computer from time to time. Maybe the lower connection prevents packet loss in other circumstances. At any rate, it seems odd for them to crap so obviously over a feature, particularly one that some of their competitors' products offer.
"Ladies and gentlemen, my killbot features Lotus Notes and a machine gun. It is the finest available."
That would have been the case with any BT driver and any BT product but crackberry. The crackberry is usually placed by operators on all-you-can-eat plans which presume only mail access to the crackberry server. The crackberry server eats surprisingly (actually the best word is phenomanally) little bandwidth. 1Kbit average per 20 users is normal. As a result the operators can afford all-you-can-eat without a problem. The moment the users start actively using it for data these assumptions go out of the window.
So, I would not be surprised if the operators demanded the feature and the feature got rolled out quietly. In other words, I would not be surprised if there is a communist hidden in the Bush.

In other news, Nextel acquitted on accusations of crippling BT data speeds. The Judge replied, "Simply, they do not offer data over BT. I could not rule them guilty over something they do not offer".
Nextel was over more than happy with this ruling and stated they will continue to not offer many other services.
I'm reminded of the time I saw this lady in a warehouse store give her baby in her cart her cell phone, she thought is was sooooooo cute, the baby would put it up to its ear... Than the baby threw it as hard as it could on the concrete floor...
