Help! My iPod Touch 3G 3.1.3 stuck on apple logo!

[JohnCydia]

So I have a 32GB jailbroken (via Spirit) iPod Touch 3G running 3.1.3 and I fired up Cydia and noticed there was an update for a package (Activator 1.4 update) so I decided to update and it got to the point where it said "Restart Springboard" but it got stuck on that screen with the little rotating loading thing for a long time so I just decided to do a hard reboot (holding power and sleep) and when I tried to turn it back on, my iPod would only get stuck on the Apple logo. From what I know, the only solution would be to put it in DFU and restore it fresh to 4.0 but I would then lose all of my data and ability to jailbreak. Anyone got any other solutions that will work? Please help!
