kitkat update coming over the air March 3
That's for France, last I heard. Sprint has not released even a whiff of a date nor has source dropped for ZVB.
Until either happens anything is speculative at best.
Heck, we only know the version because of the UA Profile.
It is just frustrating not knowing anything or being told that they have no worf of it when it is their company that is working on it so it can work with Sprint. I don't think it is not unreasonable to be given a time frame of what is going on with it and when it will be out if there are no problems with the program. But being left in the dark about it this whole time is a big let down.
I've learned the hard way after over 11 years as a Sprint customer; 1 no one at Sprint knows or will tell you advanced information on update releases, 2 when you buy your phone, be prepared to live with the current installed OS, updates are slow and handsets become old news fast to this carrier(some get left as they were at launch) 3 Sprint is a business and has a need to sell phones, long term support of a handset doesn't further this concept. 4 unless the OEM software is awesome you're better off rooting to stay vanilla Android and current.
