IPhone :: Faster Way To Delete Mail?

Am I missing a way to delete mail that seems more intuitive than what we currently have? I've read through the tricks and tips thread but if it's there I must have missed it. So far I haven't seen anything in iOS4 that makes it any easier than it was in the past.

For instance, Facebook emails. I can't turn them off because I'm OCD about status updates and I want to see all comments, and receive mail in case someone deletes one they have posted. Plus, it's easier to read emails than to go into the Facebook app and look at every status and notification that I've commented on.

Anyway, when I'm done reading them, sometimes I have upwards of 50+ emails and the only way I can find to delete them from the mail app is to tap every single email one by one, which is tedious and annoying.Is this really the only way to mass delete emails? I think the least Apple could do is make it like the photos app where you tap one photo, and if you just drag your finger along the photos it selects them as you drag.
