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 > Keyboard, and use "Add New Shortcut…" to create many keyboard shortcuts for each different signature. You can also use Mail Enhancer to get custom signatures for per email accounts on jailbroken iPad.
