Gmail will have no sound selected, Gtalk will pick one random MP3 file from my music folder, alarms will get the "Beep" sound, SMS/reminders will get a different (default?) sound, contacts that had custom ringtones will get the default ringtone, and the default ringtone for all contacts is changed too.
It's a little annoying, I can set everything back the way it was quite fast, but something else happens: for a few contacts only (random each time) I cannot change the ringtone anymore. The default one is set, I choose another one, but the new ringtone isn't applied. The only way to change the ringtone is to erase the contact and create it again (or sync from outlook to have it back).
Anyone else got this problem? I guess a hard reset will solve it, but I'm too lazy to install everything again etc.
