I have heard this is quite a common problem when unlocking Blackberry, im buying a phone which is locked to O2 and would need to get it unlocked, but i fear i may be a victim of signal problem after unlocking.
Do you mean bought legitimately unlocked, or "jail broken?"
Didn't knew you could jailbreak BB, thought they only existed for iPhones. Well what im saying is, there is a service on ebay that unlock your BB for about �1, they ask you for your phones IMEI and other details and give you unlock code.

Frequently, the BB will pick another network (since it's unlocked). When it picks a network that you're not subscribed to, you will see SOS in the top corner. Setting connection to Manual and picking the network helps, but when you travel out of a region, you may see an SOS again.
