Since today, my Milestone's been acting weird. I was adding all contacts from my previous phone to it (and I might have played around with some contact/sync settings in the process) Suddenly the phone started to slow down a bit, so I went back to the homescreen to go and check if there was something slowing things down, but I didn't get that far. It opened up my wallpaper, but without icons, and after a few seconds, showing the error: "Sorry! The process android.process.acore has stopped unexpectedly. Please try again." with as only option a "Force Close" button. When I press that, the screen goes black (status bar is not affected), reloads the wallpaper and the error pops up again. Seeing I was messing with my contacts, I thought that might be the problem, so I just deleted them all, but no success. Rebooting (several times, removing battery whilst turned off, ~) does not help. My phone is totally unusable atm, the only way I can move around is using the search key+keyboard shortcuts. Does anyone know how to fix it?
