IPhone 4 to StraightTalk
I'm trading in my HTC Inspire 4G for an iPhone 4. I currently use StraightTalk as my carrier, and would like to do the same with the iPhone. But I don't know what all I would need to do that. Do I need to purchase a sims card from StraightTalk? And would the iPhone need to be unlocked? I'm totally clueless!
