Nokia 3300 Unlocking

Hi guys. I need my nokia 3300 unlocked. I have used the DCT-4 calculator to generate the codes but i put them in and it says cannot undo restriction http://www.digital-forums.com/images/smilies/sad.gif so i think b4 i bought this fone(bought from a mate) someone has tried to unlock too many times :(.

So am i screwed or is there hope? i dont really want to buy a cable. Thanx in advance http://www.digital-forums.com/images/smilies/thumbs.gif

Needs to be taken to a decent mobile phone shop which will have a Griffin / Neelix / Twister or UFS2 device

They will be able to unlock it for you
