iPhone firmware update 2.2.1 brings minor stability improvements

No copy and paste here, move along everyone! What you can expect in the new, just-released 2.2.1 software update for the iPhone (and iPod touch) is "improved general stability of Safari" -- always encouraging -- and a fix for saved Mail images not showing up just right in the camera roll. It's like Christmas in January!
