The folks over at iFixit have been tearing apart the insides of the new Verizon iPhone, and they found that it has a Qualcomm dual-mode GSM/CDMA chip, meaning the iPhone could work anywhere in the world with many different types of carriers. iFixit says that "Apple could have supported GSM" networks such as T-mobile and AT&T with this phone. They didn't, but could they be holding out for the iPhone 5? Several sites, including Computer World, are saying that the iPhone 5 will be released on June 6th.
