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.
File Transfer
Message History, multiple dialog windows
Copy/Paste support
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.
