@coderus: dealing with nightlys, I noticed that nightly20 has some more problems in sending messages (in particular when connection switches between 3G and WLAN) compared to nightly17.. a contribution from me!
A lot of complains, from all directions and about anything , please just use it and accept the bugs until one of the devs fix it and brings out an updated version( if they have time).
erm @coderus, is your fennec-qml in the same repository as wazapp and installed a sources.list? I just received a s/w update for wazapp (0.9.17.0~nightly20)?!?
