Looking for a Better Social Media Client

I’m looking for a better social media client for keeping up on Twitter and Facebook. Since Apple does not allow home screen widgets in iOS, I would like to find an app that allows me to easily keep up with both networks on the go. I’m looking for the following features in a new client:

  • Support for both twitter and Facebook from within a single application
  • Support for the built-in twitter and Facebook accounts
  • Ability to post to either network from within other apps like Safari
