We have been anticipating an upgrade for IcthusConnect to Zimbra 5.0 for the past month. The 5.0 version was released on 12/31 but it still has about 70 Bugs, some of them, like "all day calendar appointment showing on wrong day" and "message sent from device received days later" are fairly serious and need to be addressed.

An updated version is due out "early this year". We will try and get some additional information about when we can expect it. As of now however we have decided to delay the server update until some of the main issues are addressed.
