So I have a first gen iPhone that I took out of the closet to use, I did a Pwnage tool jailbreak on 3.1.3, and when I put in the sim it has one bar or none or searching for signal. THen I rejailbroke on pwnagetool with 3.1.2, same thing. So I figured it must be hardware, it had a blown earspeaker, so in replacing that I also replaced the antenna cables and the whole antenna module. Still the same! Is pwnage tool messing with the signal? Any other jailbreak/unlock software to try and get my signal back? Much thanks!!!
