Get rid of: Sent from my HTC... on emails

[wavezero]

So generally I really like 6.5. It has a couple of annoying flaws like no letter recognizer (which is one of the reasons I'm still on a WM device), and no call history/VM alert on home page. But the the one that makes me freak out is that they sprint is now advertising to everyone else on my personal emails!

How do I get rid of "Sent from my HTC Touch Pro2 on the Now Network from Sprint." automatically at the bottom of every email? This makes me furious.

Don't stamp your advertising on the back of my new car and don't advertise yourself on my personal emails!!!!!
