iPhone 3GS & MyWi problem.

[chuk23chuk]

I was messing around with the filesystem in the mywi app, trying to crack it and it was on at the time. i made a mistake and then turned off the phone. now the phone is trying to reboot and turn on mywi and cant because the files are messed up and it gets frozen at the boot screen. I've tryed a restart (home and power) but it keeps getting frozen. anything i can try besides a complete restore?

i'm thinking thats the only thing you can do...
