Well...I'm one of those users that would rather wait for my service provider to offer the upgrade, but since I'm in desperate need of the wireless two way synch with Gmail and Yahoo! I installed the version 4.2.185 which has the 2.3.0.67 platform. So far no issues have been presented with the functionality of the device. Also to my surprise hotmail is available!!!

One question...it's true that this 2.3 platform will offer calendar synch OTA?? So far nothing new with my Calendar. I'm using T-Mobile.

Thank you in advance for the information.
