I accidentally updated my jailbroken 3G iPhone (4.1) and as expected it went into recovery mode. I used Tiny Umbrella to get it out of recovery mode, no problem. But now the iPhone and iTunes are both asking me to insert a valid SIM (my SIM isn’t working any more). What can I do to fix this? Do I need to re-jailbreak my phone?
