Just been referred to this tool from a friend of mine. It is called Mobile Registry Editor and can be found here. It lets you modify the registry of your mobile device from you PC. Much easier than using the limited keyboard on my phone.
BTW: I was talking to him about debugging my Qtek 8310 problem. It would not boot after my - ahem - cleaning up. I was suspecting that I deleted some files for my custom home screen. Luckily, I should just let it stay stay turned on for a looong time - and finally, it came up with an error message and I could switch it to another home screen layout.
