hey there, i want to give my 1st gen to my sister when i upgrade to iphone 3g. she doesn't want data, but she texts a LOT. will she: 1: be able to remove the data plan? (i know most say yes, but at&t has told me no) 2: if she is on a familytalk plan with the family messaging unlimited texting plan, will that unlimited texting plan cover the data-less iphone? (3): if either of these (both are absolutely necessary) are not possible, will unlocking the iphone (not jailbreaking) allow us to do that? thanks!
