As the title says, I just upgraded from a pearl 8100 yesterday to the bold 2 and just as I expected, I'm completely enjoying it. After using it, I don't see how I've lived without wifi for so long...Anyways, I see that there are OS updates out so I was wondering what exactly has been improved? The original one seems pretty okay for the moment except for a few apps provided by t-mobile not working 100% correctly (no huge deal) so I'd like to know before "upgrading" and lowering my battery life, messing with the camera or etc...I've updated my os on the pearl many a time but I'm somewhat doubtful that the changes could be so drastic as to further blow my mind with the 9700 in comparison to 4.5 vs. 4.2 on the pearl.
