I jailbreaked my 3GS with redsn0w and installed SysInfoPlus and SBSettings via Cydia. SysInfoPlus got the icon of some Wikipedia app that I do have installed (which is probably not the proper icon, isn't it)?

Anyway, installing SBSettings took very long so I did reset the iPhone. After it had rebooted (which also took very long) some of my apps (incl. cydia) have got the icon of other Apps (incl. those that I once had installed but uninstalled meanwhile?!). Reinstalling the apps with iTunes (or Cydia in case of SysInfoPlus) did'nt help either.

What happened? How am I going to fix this?
