I have a blackberry 8830 (sprint). while trying to unlock it i am pressing "mepd" - with i get new details on screen.
After that i am trying to press mep2 ie mep (alt + 2) - but nothing is happening.
I have the final code but i am not able to jump to the window where i need to punch the same.
I am in canada these days.
I can't help you with the unlocking steps, but I can tell you the GSM radio will not work with North American GSM carriers. If you are unlocking it to use on a CDMA carrier you may be successful, but with GSM you are wasting your time.
