How to transform an ipad4 into iphone 4? I have an Ipod 4 , and today , someone told me that using a special housing/case which is inserted in two senses , my iPod can turn into Iphone with dualsim . Is there such a thing ??? As I say I still got to watch on google and find that they can make changes , but it's VoIP service and not to any service card. I would like some clarification in this regard , how the procedure , if there are other ways and especially if it affects the functioning of my iPod or if it deserves such modification .. Thank you!
