Did the phone have this problem before you jailbroke? If you don't know, I would restore the phone and NOT jailbreak it. Use the un-jailbroken phone for an extended amount of time. If you are still experiencing the same problem, then it's a hardware issue.
Really the only damage jailbreaking can do is to the file system. And that's if you're generally moving/deleting files or you install some 3rd party software that has some malicious bugs in it.
