To reboot, just hold down to power button until the red slider appears. Move the slider and your device turns off. Turn it on again with the same button.

Redsn0w was designed for a tethered jailbreak, which means you needed to reboot tethered. But after greenpois0n rc5 your device is untetheted, so you don't need this anymore.

I have successfully jailbreaked my idevices using Greenpois0n RC5 b4. If you're using windows, make sure that you've disabled your firewall and anti-virus (temporarily), closed iTunes, ran GP as an administrator, connected your idevice, and powered it down before clicking on jailbreak. Follow the onscreen instructions to the letter, here, timing is EVERYTHING. If it says "Jailbreak failed" or something to that effect, exit and start GP again, wait for your device to boot up then power it down and try again. No need to restore.

After you have jailbreaked with GP, rebooted, and Cydia is having a tough time being downloaded and you end up with an error message telling you that you're running out of space, relax, just open "loader" and try installing Cydia again. I think this is because Cydia's servers are receiving too much download requests, just keep on trying. Lastly, after you have downloaded Cydia, reboot. Alternatively, you can install Cydia using RedSn0w.

Cheers! :-)
