Help! I'm stuck in a loop. Can I avoid hard reset?

My SPH-I300 went nuts while I was running Blazer today. It
throws
Fata Alert
Tgene.c, Line:61, null
pointer use

Reset

I've tried everything I know to do but it still comes up,
attempts to initialize the phone and then throws the same
exception.

The laptop I'd been using for backing up my data has been
down so I don't have a recent copy. I'd *really* like to
avoid losing my data. Is there any way to break the cycle?

Thank you.
