I quickpwn'd my 2g iPhone and unlocked it using TMO US, using quickpwn version 2.1-1 using FW 2.1.

Since I used quickpwn I am unable to use my snapture and videorecorder3g applications. They open for a second and then just close.

Also, there is an error when I try to open my /Applications folder. I have to go into the var folder to see my applications folder.

I didn't have any of these problems when I was on FW 2.0.1 and pwned with winpwn.

I also could change my boot images with winpwn, something that quickpwn doesn't offer.

Any ideas on what I should do to fix any of this?
