Looks like Apple managed to make a single iPhone 5 model that works on GSM and CDMA, making it a real world phone.
There have been rumors that Apple would make one iPhone 5 model that would work on GSM and CDMA based networks. Right now there are two iPhone 4 models. One supporting GSM (AT&T) and the other CDMA (Verizon). Most countries around the world are GSM based. A Verizon iPhone 4 is impossible to use in several countries. An iPhone 5 that can do both standards will solve that issue. An iPhone 5 world phone is also reducing the cost for Apple. They just need to deal with one iPhone 5 model.
TechCrunch reports that they received logs from an iOS app developer that showed several hits by a new iPhone marked as dual-mode. This evidence means that Apple started to the test the iPhone 5 on some of the apps in the iTunes App Store.
As August ends we are now entering the hot phase of the iPhone 5 rumors. We expect Apple to announce the iPhone 5 and the low-cost iPhone 4 somewhen in September. The iPhone 5 is seen to go on sale in October.
