I bought this phone in Nov. 2007, so I assume it's a 2G? I'm not sure if it's a 1G - or is there such a thing? (Can you tell I'm kind of new at this?

)
Anyway. I've Jailbroken it in the past using ZiPhone and eventually took an update and restored the whole thing.
I decided to JB it again and I used Quickpwn. I've only downloaded a few apps and my phone seemed to work fine last night. I woke up this morning and now my phone is running super slow and I can't use my phone function.
I can receive calls but I'm looking at my springboard instead of my phone functions. When I tap my Phone app I'm taken to the dial pad instead of my Speed dial or Recents, and I can't use the dial pad. After about 5 seconds it closes the function and I'm back at the springboard.
When looking at my dial pad I can't move to my Favourites, Recents or VM, so it's pretty useless. I can, however, look people up in my Contacts app and call them that way.
New Apps I installed are listed below:
- Backgrounder
- Categories
- Winterboard
- Dock Prefs
- BossPrefs
- Snapture
- Cycorder
- Cylay
- Quickgold
- Stacks
- The App Killswitch
The last app I uploaded last night was vWallpaper. Thinking this might be the issue I unistalled it this morning but it didn't make a difference.
Has anyone else run into a similar problem? I'm hoping I can avoid restoring my phone but will if it's my only option.
Any help would be much appreciated!
