LTE is apart from CDMA. Adding that radio does not automatically eliminate CDMA. Verizon phones will have CDMA with or without LTE for the next several years.
Dodgerking- He didn't say No 4G. He didn't say anything.
Personally, I do believe Apple is having trouble with their testing of 4G and battery life. The more radios they add to these phones and more power in the processor, the more we use the battery. The LiIon battery chemistry is pretty much a fixed AH capacity for a given size so unless the phone gets bigger in size, the run time will get lower as we add functions. As I was explaining to Ramy yesterday, I like the idea of all the power and accept that it requires more battery to run that power. So I have a spare battery. Iphone design doesn't permit the swap of the battery so they have to make the phone bigger or explain to their fan base that its OK to have a 3 hour smartphone.

A good way for Apple to get around this is to design an OS that triggers the radios to be on only when needed and go into a sleep mode when not needed. In other words, a user should be able to turn on and off each function manually and be able to have the phone wake up when a call comes in. I can control some of this but newer phones do global shutdown, not partial. Say I want to shut down LTE but just use the CDMA EVDO radio. ( 3G) Can't do this now. ( Note- Ramy told me of an app that permits this however) Bottom line- the software needs to be smarter in battery conservation or we will have to get used to swapping batteries or larger phones with bigger batteries.
