That's originaly an iPad baseband dud not an iPhone baseband. Provide me with the original baseband of the phone if you still remember.

I got the phone with the iPad baseband so don't know the previous baseband. :/

Sent from my iPhone using iPF.net

I see. And now you want someone to guess what could be the original baseband of the phone? It's not impossible if you are able to trace back the origin of the phone.

No I just want to know which carrier it was official on. I have heard one can find it out by the model number which I posted earlier.
Bought it for my cousin but never knew about the battery drainage issues in the iPad baseband in iPhone 3g. Will give it one more day trying to fix it, if it does well and good other wise will try to return it and get my money back
