First, current BlackBerry phones, except Passport and P9983 will not see an official 10.0.3 in any version.
After release of the Classic, at some point we will get a version of 10.3.1, mostly depends on how fast the carriers are.
Most in USA are slower than a snail crawling across salt.
100 percent correct. However, with a little Google searching and a few minutes plugged into the computer you can load a leaked version of both 10.3 or 10.3.1. It's really simple to do. I'm currently running 10.3 on my Z10 with zero issues.
A new leak of 10.3.1 was just outed today on N4BB.com
As for 10.3.1, stick with 1016 for now. Newest 1151 seems to have caused some problems for many.
BBM, Clock, Whatsapp and many others do not work. Hasn't affected everyone, but it did quite a few, including myself.
Just a heads up.
I know that leaks are available. I am just not willing to take the risk. I was hoping that I would not have to wait that long for a legitimate update...Oh well...
Since Verizon isn't selling either of the newest BlackBerry phones yet, Passport nor Classic, I don't think we will see any OS upgrade until they start selling at least the Classic.
10.3.1.1154 is running like a charm on my Z30.
Just had a chat session with VZW rep - and she was very helpful. Said they got the update on June 16th, and are rolling it out in "spurts." Not sure how long until I see it, but am at least happy to hear it's being rolled out now.
