OneTeam for iPhone 1.2.0 is scheduled for submission on Apple Appstore.
OneTeam for iPhone is a Jabber / XMPP for iPhone that supports a large subset of the XMPP protocol. It is clean, easy to use and to not rely on third party server (it connects directly to your XMPP server).
I think we have reached a point in development where we are really happy with this client. It supports a really large number of XMPP server and authentication method. One of our biggest surprise has been with iChat server that require very unusual authentication methods. OneTeam for iPhone is probably one of the few XMPP clients that now supports it.
We have been quite far today in supporting XMPP features. For example we support gateways discovery and configuration directly from the phone (and gateway contact addition as well). The next big feature is probably be going to be groupchat support.
We are listening to your comments to help us improve this mobile XMPP client. Currently we think it is one of the most usable mobile client, but we are expecting to make it even better. Your feedback is welcome :)
