One option that you could do is that you could purchase a pre-paid go-phone card for you iPhone and you could just use MYWi from your jailbroken iPhone. This would give you some more time to think of something else to do with your dilemma. Plus, the data charges come out to being much less expensive and you will note have a 2-year contract.
So I have a jail broken iPhone 4 and I use MyWi for just about everything. Literally; nearly all of the media in my household is a direct result of the MyWi connection, which tethers to my home network of 3 pc's, two ps3's and an xbox, two iPhones, an iPad, and lots of Internet tv streamed to two large flatscreen HDTV's. Im able to afford this because I have a grandfathered unlimited data plan. I recently received an email from AT&T stating that I must stop tethering to my devices, or have my account switched to AT&T's 4gig data tethering plan forever more. I definitely surpass 4GB easily to say the least, and being a student living on stipends, I definitely can't afford to pay the exorbitant overage charges for relatively minuscule additional data coverage. Also, is AT&T within their legal rights to tell me I can't use my jail broken apps? (since the Supreme Court did rule that JBing is perfectly legal right now). Is there any way to hide/reduce the total tethered data usage? Any clues would be most appreciated. I hope to have this figured out (if possible) by June 24th (the ultimatum date AT&T handed me). Please, absolutely any info would be highly prized. Hell, I could even pay pal you some $ for saving me so many future overage charges!
