I am starting a compatilbity list. I will do my best to updated it as I get more information and as updated apps come in. First off, most all regular apps should work on 3.0. The changes were not that severe for most apps to stop working. So if the app is not in the list, it probably works. What probably does not work are apps that rely on mobile substrate or any sort of springboard patching. These all use undocumented APIs.

Next is to understand why some things are not working *for you* that are listed on the “working” list. Many apps require root access and use a trick that involves the dirname command. This command was not present in some older packages in Saurik’s older repository. Saurik set up a newer version of his repository for 3.0 (which will merge back in to the trunk soon). The point is, many of you may have his older repository instead due to one of these reasons:

1) You used an early Icy without its essential updates that do not fix saurik’s repo.
2) You used apt backup to restore your packages and it restored the old repository.
3) You did not accept some essential updates.
4) Some other thing that I am not aware of. But the cause is most likely failing dirname command.

You can check if you have this issue in Cydia: Load Cydia, wait for it to do its thing then go to manage, sources, then look for Telesphoreo in the list. If you see this line of text *exactly*, you have the new repository “Distribution of Unix Software for iPhoneOS 3″ (this is good!) If you see this line: “Distribution of Unix Software for iPhoneOS” (this is bad) you have the *old* repository.

One more thing. If you install something and get an immediate spinning wheel of death, reboot. Some times mobilesubstrate’s install causes this and after a reboot it will be fine.

On to the app list:
