iPhone Matters reports that AOL will have a version of AIM for the iPhone in June. According to the post, in addition to all the usual features, the iPhone AIM client will also have an "invisible" mode and let users switch between several IM conversations.

For instant messaging fanatics who just can't wait a couple more months, iPhone Matters suggests "jailbreaking your iPhone and installing MobileChat," which gives you access to your various IM accounts from a single client.
