First all my ringtones were sounded like crap to the point I didn't know if my speaker on the phone was going bad. They sounded down right awful. I rebooted the phone and that fixed the problem. Tonight I opened my Foursquare app to check in at club I was at then everytime I hit my Text message icon, Foursquare kept opening up! I had to reboot the phone again to get it to stop doing that! I have been having more glitchy issues with my phone since I put 2.2 on my phone and yes I have 22D now too.
