Cepi, I have some problems with the newewst build (03092012).
I couldn't run Wazapp, so I looked up what it said within the terminal.
Running from terminal (wazapp_init):

UI: POPULATE PHONE CONTACTS
UI: APPENDING PHONE CONTACTS: 548


After this message, it just stays on there forever...

however, if I run ./wazapp, it will run, but without any contacts.. (can't load/sync contacts either, since it couldn't load my contacts)
