Okay, so I used to have an iPhone 3GS and had to get rid of it about 3 months ago because I cannot afford a data plan. Story of my life. Right now I'm using a Nokia E63 (which I can't stand) with the standard family plan/unlimited text. (I bought it off craigslist so no data plan with AT&T) My question is, Could I use my old original iPhone without a data plan? I would jailbreak it and block edge entirely and just use wifi. I heard AT&T scans devices and if they found out i'm using the iphone, they would automatically add the data plan to my plan. thanks in advance!
