I took the dive last night and upgraded my iPhone 3G to 3.1.2 and jailbroke it using blackra1n, other than forgetting to start it with Administrator privilledges it all went perfectly! 
I installed both Cydia and Rock and have installed all the packages below... and had no problems with them or the built in apps but this morning I tried some of the apps from the app store, facebook, air mouse, quad camera... they all look like they are loading for a couple of seconds and then just close
I am happy to restore back to factory default and try again but dont want to if I dont have to. Has anyone else had this problem and found a fix?
