After I did a factory reset, that seemed to have fixed all my problems. ROBOTO (fun classic platformer) used to run like garbage, it was unplayable on Froyo, but now it's working 95% of the time very well.
However, the stock music app seems broken now. I used to use the stock music app all the time (because of it's playcount compatibility with iSyncr), but now listening to the same songs, the music is constantly stuttering and with one song the music volume keeps fading in and out, but only at the end of the song, the rest of the song plays fine. Anyone know of other music apps that work with iSyncr's playcount tracking?
The google music app works perfectly fine, but it doesn't support iSyncr's playcount tracking.
