Hi,

About 18 Months ago I successfully did a tethered JB on my Girlfriends iPhone 3GS using the iPad BB 06.15.00.
Until now there has been no problems using Redsn0w to boot the iPhone when the power has ran out.

However yesterday when trying to boot the iPhone it would not do this and kept putting the phone back into recovery mode each time the boot had taken place. What can I do? I am desperate as I have an angry GF who is currently living away and not where I am.
I have got her to download the latest version of redsn0w but it keeps telling her that 4.2.1 is not supported currently.
So, I need to know how to either get out of recovery mode or generally how to boot without receiving the error.

If I have left information that you need to help me just ask and I will be glad to provide you with it if needed.

PLEASE HELP!!! Thanks
