That is my dh's issue now. He just went back to his blackberry. The iphone he had he gave to our oldest son. It is the iphone 4 and it just didn't work overseas anywhere he went.
I think he just needed the iphone 4s for the sims card. But the blackberry works every time every where he goes.
But we have all mac computers, he even has these at work, and he has the ipad for work and we have one for home. He is having a hard time getting all of his contacts to covert from the mac onto the blackberry and that is making loony tuney.
