I have been jailbroken on my Iphone 4 since Jailbreakme.com came out and haven't had any issues. In the last day or so my reception bars will suddenly drop to no signal, even in places where i get 5 bars normally. It will randomly spike up to 1 or 2 bars for a few minutes and then drop to no service. This seems to be happening everywhere, at home i have a microcell and it will connect to it and then randomly drop to no service again. Is there any chance this is related to being jailbroken? I have tried restarting, going in and out of airplane mode but nothing seems to work. Any help would be greatly appreciated.
