im borrowing a mates olld phone till i get my new one but it wants a retriction can anyone help imei number-357603001284504 thanks

Sorry not quite understanding the question.

this its an unlock code

Have you looked on eBay mate, I managed to unlock a blackberry on there for 99p if you give them your imei number

Unfortunately it's not a "free" unlock on the 6280, but it is fairly easy, and quick, to do if you have the right equipment.

Which network is it locked to ?
