I have a couple of questions, I hope some of you fine people can give me an answer
Can someone tell me why the 6510 has a polyphonic tune when the phone is turned on, but all the ringtones are normal ones? ....is there a way to enable polyphonic ringtones on it?

Another completely different question is:
I got the unlock codes for my phone and when I typed them in (#pw+code+code number#), I got a message:
Cannot undo re-striction (little flashing stop)

Does that mean my phone is already unlocked? .. or does it mean that the codes are no good?
