I jail broke my 2.2.1 iPhone 3G. I bought the phone in the UK where it is on O2 (telephone company). I live in Bangladesh.

With the O2 Sim in the phone I get a signal (from Grameen phone which is a Bangladeshi telephone company).

I don't get a signal with my Bangla link SIM or even with my Grameen Phone SIM.

So I assume I have another step to take to free up my phone. Can anyone please clue me up?

I'm guessing you'll need to unlock it with yellowsnow...

Aren't the iPhones purchased outside the US factory unlocked thus not requiring software unlocking with Yellowsn0w?
