Okay so I have a iPhone 4 on Straight talk unlimited for $45 ....I want to use the same plan on my iPad but I don't want to pay a extra 45 plus the 45 for my phone... So is there a way I can use 2 sims on one account or clone my sim or something like that? If so please let me know. I'm open for suggestions also ... I have iPad 2 black wifi+3G 32gb on AT&T.
