hello ..
hr u this is my 1st thread...
if u forgot the securtiy code of ur fone then ...
You need two mobile phones.

1) Do _not_ turn off the mobile phone!
2) Remove the Memory Card (MMC) from the locked phone and put it into a
second mobile. Install FExplorer on the second mobile phone. Create
the directory E:\System\Recogs and copy thc-nokia-unlock.mdl into
this directory.
3) Remove the Memory Card and place it into the locked phone.
The THC-NOKIA-UNLOCK program should start after 2mins.
4) Remove the battery. Remove the MMC. Put the battery back and restart.
The Phone Lock has been reset to "12345".
