Hi, I've scoured the forum but I can't seem to find anything that answers my questions.

My iPhone 3G was bought from America. After initial failures in unlocking it on my own, I took it to a computer store where they did it for me. All was well. I used a Maxis 3G post-paid sim card and I could download Apple Store apps, etc.

Unfortunately, I stupidly (accidentally) updated 2.2 firmware to 2.2.1. My sim card could no longer be identified. Desperate, I activated my phone with a prepaid AT&T sim card I had on me. The latest back up on my iTunes for my phone has the American number registered, along with all the files on my iPhone.

I downloaded Quickpwn 2.2.5 because it's said that it can unlock this new firmware. Everything went smoothly, but like when I first got my phone, I can't make or receive calls (immediate failure) and I would like to do it on my own if possible (since I'm tight on cash right now).

Question 1: How can I enable calls on my iPhone?

Question 2: Can I restore my latest back up after fixing this issue, or will I have to input everything from scratch?

Thanks very much.
