I know this may sound stupid but how do u do the keypad lock on 3660 or was there a timeout keypad lock?

And then er...regarding the ringtones..i use the recorder and only manage to record sound for a duration of 1 min. Is there anyway i can upload my mp3 to the phone like convert it to the phone format and comprise it or something and send it to the phone.

I saw some ppl have a song for a ringtone and that song is very long seem like the whole song been recorded or something.

Thanks in advance... :D

Keypad lock:

Option 1: Left "softkey" ("Camera" by default, I think) + '*'.

Option 2: Press the power key briefly and choose the lock keypad option from the list.

Both methods are printed in the User's Guide. Lots of other useful pieces of information, if you're new to Series 60 based phones.

There's also an application JJLKeyLock that can lock they keys after a set period of inactivity:

The sound recorder records only 1 minute max.

There are programs that can convert MP3's to other formats like WAV that the phone can play.
