Tried a hard reset? (Holding down VolDown and Central Softkey while pressing Reset "hole") Before that make sure you saved all your personal stuff with PIM Backup for example. And don't forget to set the "Save to" folder to "Interner Speicher" instead of the default "Storage Card". New O2 ROM can be found here:
