Amid all the new feature set, the main element of iPhone 5 as a phone is the newly added support for LTE and HD voice. In the U.S. three carriers will offer LTE supported iPhone 5. Six Canadian operators will offer LTE support for iPhone. In the UK, consumers won’t be disappointed either. And, what’s refreshing is that the iPhone 5 is going to launch HD voice with a handful of operators. The new iPhone will be available in separate GSM and CDMA versions.
