Samsung BJ2 i617 unlock?

[medmansri]

Currently locked to AT&T, is it possibly to unlock it?
I've tried a couple of methods on this forum, unlock services on ebay, and AT&T it self, but there doesn't seem to be a way to unlock the darn thing. AT&T said their system doesn't provide a code for this model.

Has anyone been successful at unlocking this model? if so, please let me know how it's done. thanks!

See this

I have an italian branded i600... and I have unlocked in this way...
Here it is:
1. Download Microsoft Security Manager for WM5 and install it on your PC
2. copy tools.cab to your device and run it
3. connect your device with Activesync and start Security Configuration Manager on your PC
4. select "Security off" and click provision
That's all...

For Me it's working
