We've been hoping someone would get this together, so we figured we should shout about Shape Services, which has introduced a free instant messaging client for the iPhone which is compatible with many different IM services.

"The award-winning IM+ All-in-One Mobile Messenger for chats within AIM / iChat, MSN / Windows Live Messenger, Yahoo!, ICQ, Jabber, Google Talk and MySpaceIM from any iPhone and iPod Touch.

"Communicate with friends and colleagues wherever you are regardless of location and mobile operator," the App Store blurb says - the product's doing pretty well - it has shot straight into the top 25 downloads on the service.

Main features include:

- All public IMs in one client. 

- No cost per message.

- Simple and user-friendly interface.

- Inbox view to keep an eye on all open dialogs and unread messages.

The developer behind the software develops a wide range of solutions, with particular regard to mobile platforms.
