Simple hack provides unlimited SMS on T-Mobile
If you're a T-Mobile customer and SMS junkie, there's apparently an easy way to get unlimited SMS service by switching your default sending options from GSM to GPRS. Of course, given that T-Mobile only charges $6.99 a month for 1,000 messages, you have to be really frugal, really into SMS or really addicted to trying out new hacks to do this
(for the record, we fall into the third category, so don't go calling us cheap). We're assuming this violates the terms of your user agreement, and that T-Mobile is working on a way to thwart it, but for now, here's your chance to become an SMS spammer.
