This app allows you to chat using your gmail account or other jabber account. I’ve tested it and it works. Very fast over WiFi. Simple setup, just type in your username and password. You can use a proxy if you’d like but it’s not necessary. I think it would be nicer if it looked more like the stock SMS. I don’t like going to a separate screen to type than the history page. It would also be kewl if a badge appeared when on the springboard when you have new messages. There is also a User button in the buddy list menu that doesn’t do anything for me. Available through the iSpazio Source.
