iPhone 3GS - settings crashes back to springboard

[NutFlush]

Hi,

I got this problem with my 3GS, running 3.1.3 (plus the latest Spirit version) with iTunes 9.2 on a PC with XP:

When I try to change some settings I get kicked out of "Settings" back to the springboard. This is very strange and happens when:
1. I try to change my timezone (I can toggle the automatic detection, but when I try to change the city it crashes).
2. I try to change the password or other settings in any of my email accounts.

Please help!

Thanks!

I'm pretty sure Spirit doesn't work with iTunes 9.2

Well, going back to iTunes 9.1 didn't cure the problem...
