Text based chat (IM) features:

★ Talkonaut is a J2ME (Java to Mobile Extention) application, designed to run almost on any mobile handset with minimalistic MIDP 2.0 support.
★ Talkonaut is based on Jabber (XMPP) protocol. It allows you to connect to Google Talk servers or to any other Jabber servers using any domain name in your JID, thus evaluating free chat with any Google Talk[tm] or Jabber user.
★ Talkonaut runs in a full screen mode on your mobile and provides non-standard user interface especially designed to meet users' needs. Talkonaut evaluates a Google Talk[tm] like user interface, yet is not a copy of Google Talk[tm].
★ Talkonaut is designed to use GPRS or Wi-Fi service. Talkonaut reconnects to Jabber server each time a data connection is lost and resends buffered data, thus none of your messages can be lost.
★ Talkonaut allows you to manage your list of contacts by adding, removing or renaming contacts. Your contacts are stored on Jabber server, but not on your phone, so any changes will be visible to you while conneting from your PC or from any other mobile with same credentials.
