Hi, just opened up my sim tray on my iphone 4s to find this little sucker in there rsim5. I know its there to unlock my phone but what else does it do or could it do? Can this send my messages to a linked phone or worse, send off my bank details (that you have to enter for a new apple account/after a factory reset) am i being paranoid. I hope so. also does this mean my phone is jailbroke. Not too happy as i thought i paid for a propper unlock, not some weird chip on my sim card.
