Does anyone know whether there would be a problem "sharing" an iPhone on a couples plan? I am inclined to get a voice only plan since the value of internet doesn't presently approach the cost for us. But I need a new phone and an iPod, so an iPhone is an interesting option. If I get one iPhone and one regular phone on a couples plan, can anyone see a problem with switching sim cards between the two if we want to "share" the iPhone sometimes? I could see a problem if one sim card had a data plan attached, but if they are identical customer profiles should it work?
