GMail for iPhone: Moving signature above quoted text

By default, GMail for iPhone puts your signature below any quoted text from the message you're replying to. This means that the quote is sandwiched between your message and your signature. As far as I'm concerned, this makes absolutely no sense. Sparrow for Mac puts the signature above any quoted messages by default for example.

Is there any way to move the signature to where I want it to be? Or will I have to make a shortcut and type that in every time I want to send an email?
