iPhone 4 - Can't change homescreen or lockscreen background...any help?

[prazer]

Hey guys...
Can anyone help me out...Using the settings app...I cant change the background or lockscreen settings...Im running an iphone 4 iOS 4.3.3 winterboard (i've deleted and reinstalled to no avail) lockinfo, callbar, mobilenotifier. Nothing changes the wallpapers on the homescreen. I'm really at a loss.

Likely a theme or mobile substrate item is causing the problem.
Un-select one or all themes in Winterboard and test.
If that doesn't help, use SBSettings / More / Mobile Substrate and disable dylibs and test.
If a dynamic library was at fault, re-enable before uninstalling.

I can't find dylibs in sbsettings...hmmm...but now all of a sudden it works?????? WTH? Oh well...
