As we all know the new iphone has got us all excited! I have two lines on my account; Mine and my gf's. Mine is not available for upgrade hers is. She doesn't care for the new iphone she's happy with her 3gs and not that into technology stuff. She rather buy a new pair of heels and some clothes then get the new iphone. So my question is what if I upgrade her line to the new iphone when it comes out and then just put my sim card in it. Will I have the new iphone on my phone number??? Will her phone still work as well? Has anyone done something like this before?
