IPhone Message Apps for new OS 5.0

[PSULionRP]

Are there any iPhone Message Apps that are compatiable and good for the NEW Oprating System 5.0 and that you might recommend???I had a couple...namely nimbuzz...that seems to be whacked now that I upgraded my OS to 5.0. I can no longer select a pic or a video, etc..Sooooo I'm just wondering if anyone that has done the upgrade to OS 5.0 using an iPhone 4G could recommend a Messaging App that seems to be really good and is either already upgraded or 5.0 or the transition doe not seem to have taken any effect.Thanks in advance for your review and hopeful for a reply.PSULionRP
