Went to Verizon today for phone upgrade. Undecided between Droid Mini and Razr M. Leaning toward the Razr M but have software questions someone might answer. 1. Is it pretty much certain that Verizon will be releasing the 4.4 KitKat update for the Razr M? 2. If yes, will the KitKat update be limited to only Unlocked/Developer Editions of the Razr M? Moto site says ALL Razr M's but other sites say only Dev. Ed. will get it. 3. Do Developer Editions/Unlocked Razr M's even work on Verizon? 4. What the difference between Unlocked and Developer Edition? 5. Will the Razr M get Touchless Control feature with the KitKat update? How has everyone's real experience been with battery life on the Droid Mini? I passed on the Droid Mini today because of so many comments on short charge life.
