What network are you trying to unlock it from, I know the people at quikunlock.net has solutions for many network unlocks on their site, I recently unlocked my phone from the Rogers network in Canada with quikunlock.net, it was cheap and fast.

good post

You can contact one of the unlocking vendors here: Cell Phone Market - Cell Phone Forums

I am new to this site i was hoping someone on the forum could share the network unlock code for a samsung qalaxy ace 2 x s7560. I would really appreciate the hand. Thank you for your time.
