Hi,

i need to unlock my new Samsung X660. not urgent but soon. i`m going to a foreign country so i will use an another sim-card. i`ve looked through posts here and found how to unlock samsung x600 and other models but it doesn`t work with my phone. i tried the code #*7337#, the phone has reserted and deleted all the settings now if i put the sim card what the tekephone didn`t accept i´m asked for PIN and when i give it the message "wrong card" apperears but it´s still locked. But i still can use the phone with the original card.
can somebody help me? what should i do now?
thanx for any help...

p.s. will i lose the phone warranty when it`s unlocked?
