I've been dealing with a strange problem with my iPad 1 for a few weeks. Instead of displaying a "3G" label at the top left corner of my screen, it now shows a "E" label. Since that time, the connection is VERY slow, like 56k slow. I've called my ISP and there is nothing wrong with the actual service.
My iPad is jailbroken and I have recently installed many Cydia apps that might cause this. My ISP recommended restoring my iPad however I wanna wait for iOS 5 untethered jailbreak for this.
Do you know any apps that might have caused this with some people ?
