On my jailbroken iOS device I can see that all App Store apps are located in individual directories in /private/var/mobile/Applications/ named with a long identifier (eg 2075E7C0-D2EF-5A4F-B356-3EECDC9F7B38). Does this serve a purpose, other than preventing conflicts between apps with the same names? Why don't Cydia apps stored in /private/var/stash/Applications/ have such an ID in their paths?
The identifier is generated randomly on install and it is one of the sandbox requirements.
