Please, if it's possible, i need the unlock code for a Nokia 3510 mobile phone.

P.S. Can this damage my phone,i just bought it and i'm not very familiar with this unlocking method?

You you can not damage the phone using this method, remote unlocking is the safest way to unlock a phone.

Sorry to disturb you again, but none of these codes worked..
Is there a limited number of tries,before the phone refuses to accept any other unlocking codes?I'm asking you this, because at first it gave me an error (something like "wrong code") and then itgave me this message "cannot undo operation".Does this mean i cannot unlock my phone anymore?
I've tried this way:
*#06# to find my IMEI.After you gave me these codes,I removed my SIM card, i turned on the phone and dialed:
#pw+??????????+1#
or
#pw+??????????+7#
where ?????????? are those codes you gave me.
Please help me unlock my phone, i'm kinda worried not being able to unlock it...
Or can you generate some other codes for me?
P.S. #pw+??????????+7# should eliminate any locks,right?I mean i don't know what kind of lock code i have to write,i heard that ...7# should eliminate all locks...
Thank you in advance
