Greetings all -- After hitting the "Install" button on jailbreakme.com, the Cydia icon appears on my screen and the status bar shows the software loading, but as soon as it starts installing the icon disappears. Rebooting doesn't help. Must be some kind of conflict, but where? I've closed all running/background programs. Works fine on my iPad 2. Any suggestions? (Yes, I'm running 4.3.3) Thanks very much...A.
