Hi mate,

sucks that you've had a bad experience. I'd have been inclined to send the little red one back and ask for a replacement.
fresh install of the OS seems to fix issues for some but i guess what some people can live with, can be a deal breaker for others.
the biggest problem is that some of the issues reported so far seem to be random in nature, both with regard to occurance and scenario.

I'm not sure how backwards compatibility with side loaded apps is going with the Q10/Alpha C.

i know repackaged BAR file for skype (Q10 build) is working ok on the Z10 and is just letterboxed. I'd assume the screen size rendering might cause problems on the smaller 3.1" screen with repackaged APK files going the other way.

Seems most apps for the Z10 will be available for the Q10 (if not already listed in BB World) on release.

It's the waiting that sucks.
