I cant wait for 5.3 the only issues that I have no are that sometimes I do not get texts or missed calls (could be a verizon issues), because I do receive calls and texts. Also, for some reason any ringtone I have set up for individual contacts does not take. All calls use the default ringtone. I also set certain calls to go directly to VM, but it doesnt I still receive those calls.
Angry Birds Rio plays like crap on my phone. It has done this for a few months, so i am pretty sure it is the limitations on the droid memory and not the app.
