ShuttleTrack
Works well if connected via Wi-Fi, but takes 12 minutes to load using EDGE (at least in one test). May need to work on a "mobile" version of ShuttleTrack to make it useable.
People Directory
Phone number cannot be tapped to dial (same problem as other mobile devices). Alternative solution can be built using LDAP.
Whereis (Campus Map)
Stellar
Can log in using username and password.
ECAT
Not going to work due to lack of personal certificate support.
