Hi guys wasn't sure where to put this so I put it here. I have an iPhone 4 GSM purchased from Hong Kong which is factory unlocked, i also have an iPad 2 3G which I use in USA with the AT&T microsim that came with it. Thing is, I want to use my ipad microsim inside my iPhone in USA. It is gsm on ios 6 beta 3 and is unlocked. Thanks in advance if u can help.
