just for the record.
it does not have issues with z-push it does have issues with active sync protokoll
i know at the bototm line its the same but dont blame zimbra backend from liverpool or z-push for that - those issues are same with microsoft exchange
blame android AND microsoft for it because of that troubly activesync protokoll
about your device - ok i dont use htc but just take a close look on
Wildfire S Android Development - xda-developers
this thread provides with roms you can use and also with tutorials how to do it
however htc do not release so upen as samsung do so you dont get newst androids (sadly)
btw: dont go on 3.0
many people dont know android 3.0 IS NOT a later version of 2.3
its a parallel development tree made for tablets in first place - so its very likly that a 2.3.3 works better then a 3.0 becuase its newer
stick to 2.xx versions until 4.0 comes out (4.0 is next generation for phones and tablets) - try to get hands on 2.3.4 or 2.3.5
hope i could help
