I just recently put 2.2 on my phone and am very happy as this has fixed my wifi issues and losing service while sitting in one spot, however I notice now 2 new issues which may be a nuisance.
1. My music no longer automatically goes to the next song once one is done, but worked perfectly with 2.1
2. My computer is unable to find drivers to recognize my phone as "Droid X" and simply recognizes it as a external drive, so syncing with windows media player may but media in the wrong folders, but I imagine there will be drivers once it actually is released by verizon
As far as music goes, I have played around with shuffle and repeating options and nothing seems to work. It just seems to stay on whatever song I select, even after clicking the arrows to go to the next song, every song has to be selected manually. I understand that more likely than not this was "leaked" on purpose so motorola could get some free beta testing out of it. Has anybody else had similar issues or any issues in general with froyo 2.2 though?
EDIT: music issue was fixed by reboot, not sure what caused it
ANOTHER EDIT: I figured out what caused the music issue, for some reason when I use the search function and look for an individual song, and select it, it will be stuck on that individual song, and if I go back to the music list and select another song it will stay stuck on the next song I select, and the only way to get out of the loop is to go back to the music list, click the menu button, and select play all.
