Interesting, thanks for the info. I didn't realize that Sprint's recent CDMA radios also supported Rev B. I sure hope they do that, would definitely keep me on Sprint - but somehow I doubt it. I remember back years ago (like 2005'ish) when EVDO first came onto the scene and it was widely thought that all the CDMA carriers would quickly jump right up to Rev B. (rev B also supports simultaneous voice/data I think..) Obviously that never happened. In fact, are there any CDMA networks anywhere in the world that are operating EVDO Rev B? Maybe Korea??
The problem with LTE is the same beef I have with Wimax, which is that it requires a separate radio. Battery life is always tenuous on modern smartphones, and the thought of having a 2nd cellular radio on all the time just bothers me. Especially a radio that is as power hungry as Wimax or LTE. That's why I like HSPA: decent data speeds, simultaneous voice/data, and all on the same radio. Someday when LTE is everywhere then it won't matter since we'll be doing voip on LTE, but that "someday" is a long way off methinks.
You don't need a second radio. The second gen LTE chipsets are all multi-mode that do CDMA/evdo/LTE all off one chip. Wimax never got those because it's a boutique technology.
As for Rev. B; when it was introduced carriers took a long hard look at it, but passed because they wanted to focus on 4g instead. For Verizon especially, their rev. A speeds are more than sufficient and stable, so there was no need for rev. B.
In sprints situation, rev. B would be a great stopgap until they begin their LTE buildout, and it's actually doable since they're replacing all of their network equipment anyways due to network vision. Or in other words, the money is going to be spent regardless, so they might as well jump to rev. B in the process.
