Manage iPad multiple email signatures on iOS 5

I'm using personal and business account for email and have update my iPad 2 to iOS 5, but there is no way to manage multiple email signatures. I just want to have different signatures for each account. How can I do that?The iOS 5 is still officially lacking support for this feature. Apple hasn't made that option available.If you need to do that, you can try the tip. Tap Setting > General >
