Sorry for a post thats probably been made a million times I just need DIRECT confirmation about this before I go any further. I wanna use my old 4gb iPhone that I dropped and cracked the screen becuase I want music again, but I'm now using a blackberry with unlimited texting and no data. CAn I jailbreak the iphone and unlock it and use my ATT sim with unlimited texting abilities still? Can I turn off data on the iphone? Sorry for the most likely repost, I just need answers directly so I can be certain.
