on iPhone 4 with 4.3.1 here incompatible:

PkgBackup (Restore button nonfunction, perhaps a cydia 1.1.1 issue)
Snappy (black or none camera picture)
Update Hider (not installs in app store)
5-Row Keyboard (with 5-row 4.3.1 fix from cydia working)
PhotoAlbums+ (beta from beta repo works)
ToneFX2 Pro (not exchanges unlock sound!?)
Phone Buzzer (vibrates only 1-time minimal, nearly unrecognizable)
Celeste Bluetooth (unable to unstall because of action menu)

my other 100 tweaks are working good, need time to test all features,
i only miss Phone Buzzer and Celeste.
