The holdup is BlackBerry has to release an update that doesn't blow their phones out of the water. I've been reading the CrackBerry forums on the latest leaks. Quite a number of BB10 owners are still having issues with these updates. Verizon is always dead last when it comes to OS updates and BlackBerry in general. I'd be shocked to see any iteration of 10.3 show up from Verizon any earlier than June.
BlackBerry Z10 rules! BB10 OS 10.2 rules! BB10 OS 10.3...not so much...
That doesn't help with VVM though. Verizon needs to get their stuff together and get this out. Personally I'm fine. I use a work around for it, but the usual customer shouldn't be stuck on 10.2!
I've already updated several times on my own. If you look around you can find ways to upgrade with out Verizon. I've never had any problems with my Z10 after upgrading.
Got tired of waiting.
Since Classic was updated to 10.3.2.840, this upgrade was only 9mb.
Also mandatory. Likely to do with states new privacy laws, like wiping device.
