With IM+ the most popular instant messaging systems, including AOL, ICQ, MSN and Yahoo! Messenger are available on your Pocket PC 2002 and Windows Mobile 2003.
The main IM+ features are:
IM+ makes direct connection to the supported services, without any "gate" in the middle. It is very important because it means that you connected to your favourite services as a full rights user and get all the messages and events immediately just as if you were connected with the standard client.
Message History, multiple dialog windows
Contact list management functions, including facilities to add a new contact, to delete a contact and to change nick of a contact.
IM+ keeps the contact list information on the respective servers. So, IM+ and your ordinary desktop client always use just the same contact list. E.g. if you add a new buddy in your contact list with IM+, and you will see him in your list also if you connect with your desktop client.
