Best all in one messenger app?

I know each user has different needs but YIKES would that be one giant inbox for me if all of my sms, mms, e-mail, IM's, etc. flooded into it. Even on my BB, I make sure to filter my unified inbox to just my e-mail accounts.

But to answer the question, I haven't seen any app that does consolidation of all of that. Just ones for e-mail specifically or IM specifically.
 
Sense actually does this within each contact's page. Still, would be awesome for something easier to use.
 
What about something like Helio had?

Helio had the Ultimate Inbox. You would get SMS/MMS, IM, email, ect. in one area but each was seperated. So basically, the inbox had subsections instead of having a seperate app for each one.

Does that make sense? I hope I explained right.
