I hate to thread hijack or anything, but there were some comments here about Gmail not being properly threaded on WebOS, a problem shared with the iPhone. My solution to this, for now anyway, is that I've been switching back and forth between the Gmail web app and the native Mail app (e.g., using the web app for indicating spam, starring messages, search, etc.). This approach seems to be working, but it's still annoying to need to flip back and forth.

Anybody else have a better solution?

Also, driving even farther away from our unproductive flame-fest, has anybody tried the Gmail-as-Exchange-Server thing for the iPhone? I still haven't bitten the bullet and done it. I'm curious where it's going to cause me grief versus where I'm going to love it.
