Ok I have a blackberry 8830 which for verizon will include a verizon/vodafone sim card. I have read about people using vodaphone in other countries. But seeing the gsm/cdma issues always comes up. I have activated the card but for some reason I cannot find an unlocked iphone. People around the world have used vodafone sim cards in unlocked Iphones. But will this work in the good old US of A. So basically what I am asking here is, will a blackberry 8830 sim card for verizon work on an Iphone. If i can find somebody who has an unlocked phone I will update my attempt at finally having the iphone on verizon.
