Various new companies are trying to develop towers and other forms of transmission technologies that could handle such surges.
Actually the number of calls in one cell is limitited to the availability of slots in the time-division of one frequency and the number of available frequencies near your location (not necessaririly your cell). And for other types of communication than voice, like SMS (runs over the signalling channel via the MAP protocol), is limited to the bandwidth of the signalling channel (C7, or A7 in the US).
And regarding emergencies: In GSM-networks it is allways possible to put the network into emergency-mode. In emrgency mode only subscriber with a special flag in their subscriber entry in the database (Home Location Register) are allowed to place phonecalls. And 911 or other emergency calls allways kick one call out of the line when there isn't no more bandwidth. Fun for new years eve. Tell your friends to call 911 and hang up immediately. 30 friends bring 30 free lines for 30 friendly phonecalls;-) (Don't do this at home, kids, GSM only)
The point that the basestations and "towers" aren't powerful enough is just... Well, NYT:-)
Ahh, how common is GSM in the US anyway? Is it as common than in the rest of the world or is it still just available in major cities and sourrounding areas? Just for comparison: GSM coverage in Germany is ~97% for all providers in the mean. What is it in the US or Canada? (Except deserts, mountains and other very remote areas)

I personally heard first-hand that people are using their big networks (/20 and bigger) for falsifying online-polls and get paid for it... That person even told me that he wrote a handful of small scripts to change the reverse-lookup of the IPs constantly to hide the manipulation. Whatever that is good for.
Mostly the online polls are somehow connected to a company ("vote for your favorite petshop in your area") who are willing to pay for it. But... What are online polls worth after after that?
Siemens in Germany is laying off ten thousands of workers; the whole telecommunication biz in Germany is on the ground. So why are a couple of hundred workers at Corel are worth a headline at/.?
Nobody is talking about the thousands at Marconi, Alcatel, AT&T, Siemens, name a company.
Sorry, i might be a bit pissed of, but sometimes i don't get the point about selective recognition.

Yes, it definetly matter to you, but you don't need special hardware equippment to change your IMEI. You can change the IMEI of a lot of cellphone (I know about Nokia and Siemens) with a serial-cable and a piece of software. This just needs hacking-skills and not some magic black box stolen from some gov-lab...
Anyway, you can not prevent people from steeling something and reselling it just because you forbid them to change the serial-number of a car with a welder. It's done with cars, and music... choose a product. Look at the DMCA - it did not prevent the people from buying and using MOD-chips in their DVD-player or using DeCSS.
Don't get me wrong, thievery is wrong. But this is just another stupid law which won't change anything imho.
6. It is expected that the creation of these new offences, taken together with the implementation of a handset barring system across all networks, should help remove the incentive for mobile telephone theft.
How silly! It doesn't matter a thieve anyway. It will only bring the buyer into difficulties, maybe he even doesn't know that the cellphone is stolen... Alex.
It's pretty funny to read that life isn't that common although other scientists claimed the opposite a couple of weeks ago.
Here is another bit with some comments (sorry, german, use the fish).

We in Germany have the same discussion at the moment, with one difference: We allready have a national ID-card. There where privacy issues in the eigthies when the government introduced the first fully machine-readable id-card, but it was introduced anyway. There is also a nation-wide register of places of birth and current residence, so the whole id-card issue is nonsense. The ID-card is just a thing that proves your identity. By the way, they (the government of Germany) want to introduce bio as well, but consultants told them, that the false positive/negative and real positive ratio is to bad at the moment. I hope they listen to them...
I suggest "Design of the UNIX Operating System" by Maurice Bach (ISBN 0132017997). It should stand right next to "Operating Systems: Design And Implementation" by Andrew Tannenbaum (ISBN: 0136386776).

I get sometimes spam which claims that this spam isn't even spam. As an evidence for that they post a.signature like that:
This message is sent in compliance with the new email bill section 301. Under Bill S.1618 TITLE III passed by the 105th US Congress, this message cannot be considered SPAM as long as we include the way to be removed, Paragraph (a)(c) of S.1618, further transmissions to you by the sender of this email may be stopped at no cost to you by sending a response of "REMOVE" in the subject line of the email.
What's up with that bill ? Is that true or is it just FUD, a lie ? Since i'm not from the US i don't know anything about their laws.
Anyway, if i reply i only get a "user killed" or something similar...

The cellphone will work with a faked IMEI.
