Samsung SCH-i730

I do not believe this has been covered, or that this is appropriate for this forum, but I was wondering if someone could help me or direct me somewhere in installing instant messenging software on the i730. I am not an AOL client, but I have an AIM account setup. I have tried Wemessenger and Agile Messenger, but was unable to sign-in with my username.

So if anyone has any troubleshooting advice or other information, it'd be appreciated.
