This is something to take into account when upgrading to 2.1  Some of my jailbroken apps do not seem to work correctly. Videorecorder3G does not load at all and IntelliScreen seems spotty at best.

I may have a conflict, (I have a feeling it could be Categories; although the jury is still out on that) but I really hope not, Categories became an instant MUST have as soon as I loaded it.

I will keep testing and keep you’all updated.
