My Nokia 3410 request a PUK code.

I am very stupid, but lost my PUK code.
I already called my provider T-mobile (NL), they can only sell me a new (prepaid) SIM card including a new fone number!
I do have all other papers, like prove off purchase.

I am not very happy with above.

I read in this forum there is no way to get the puk code. Is this true?

I also read there is a posible way to connect a cable to a PC and reset the security code. Do this solve my problem?

thanks

Arie
