You have been asking since yesterday about the applications compatible with iOS 4 and here I have finally found the official list initiated by MuscleNerd and completed by users/developers. If you want to find out which applications are compatible with iOS 4, visit this pageinc where you will find a good part of the applications in Cydia and the mention of whether or not they are compatible with iOS 4. The list should be accurate considering that the changes in the list are made only by members of the Dev Team, so I would say that you can rely her. Don't get your hopes up too high yet, many applications are not compatible with iOS 4.0 because the developers had access to the jailbreak only yesterday when it was officially released.
