I upgraded to this new OS offered from Tmobile. But my issues are that I lost the use of the Mute key. And it seems to have signal strength. There are changes. Themes are acting strangely. Has anyone else experienced issues and should I downgrade my OS. Thanks for the help Posted via BlackBerryForums.com Mobile
IF you have the 8520 or 9700, the mute key change is here to stay, if you downgrade, plan on staying there because from my information, RIM is not planning on changing that.
Tmobile Upgrade OS .330 to .714
