Hi,
I've recently upgraded the firmware of my n6630 to v5.03.08 17-08-05 RM-1. Some interesting new features appear but some old ones disappear.
For instance if a contact with a miniature calls me it appears his/her own pre-set photo in the incoming call balloon. But if I put an mp3 in "e:\nokia\sounds\digital\" it won't be shown in the OS ringtone list like before. Any clue? The only scam I found this far is to make use of the phone built-in memory "c:\nokia\sounds\digital".

P.S.: my phone is NOT sim-or-whatever locked.
