Hi all,

Just tried to update to iPhone OS 4, first download failed with a "Firmware Corrupt" error, so it downloaded again. It seemed to succeed, but then got so far and stopped with an "Unknown Error Occurred (21)", and now my iPhone is stuck in recovery mode.

What on earth am I supposed to do now?

I am not pleased =(
