As I already told you, iOS 4.0 GM is not yet 100% compatible with all applications in Cydia, not even with Cydia itself considering the fact that it refuses to update the sources in a reasonable time and every time it waits a few minutes for this operation.
First, let's see the applications that are NOT WORKS on iOS 4.0 GM:
- All applications that use mobilesubstrates;
- iFiles;
- iBlueNova;
- MyWi;
-
SBsettingsl
-
Winterboard;
-
Insomnia;
-
iTypeFaster;
- Mobile Terminal;
- Safari Download Plugin;
- BiteSMS.
And now the applications that work with iOS 4.0 GM:
- Snes4iphone;
- GpsPhone;
- blacksn0w – a modified version;
- iSteamy;
- dTunes;
-
Ness 3;
-
Emulate.
If you were interested in switching to iOS 4.0 and jailbreaking it, I recommend that you wait for the official release of iOS 4.0, because by then all the problems related to the new iOS will be solved.
