If you don’t want to miss any IM service in your mobile then Mundu IM should be your choice.You can use yahoo, msn, gtalk, aim using just one IM. You can download trial version.

When evaluating Mundu’s competitive environment, it becomes clear that its IM service takes aim at Agile Messenger, which currently charges customers $44.95 for lifetime use. Based on my findings, the experience is similar, but Mundu IM’s $11 one-time fee puts it over the top and makes Agile Messenger less appealing. It basically made for iPhone but it’s available for BlackBerry Now.
