If you're using AT&T's email-to-SMS gateway, use number@mobile.mycingular.com rather than number@txt.att.net. The mycingular.com address always uses the same sending number, so it appears as a single conversation that can be deleted with one swipe, rather than one per message.
Not sure if other providers have a similar setup, but this one saved me from ditching the iPhone entirely. Now if only I could use my own custom SMS ringtones....
