Listened to the Mac conference that just wrapped up at the WWDC. I won't go into specifics, but here's my list of Tweets covering some of the info regarding iPhones.
# $99 for an 8 Gb iPhone 3G. iPhone 3GS (the S stands for speed) will be $199 (16 Gb) or $299 (32 Gb). It's 2x-3x faster than a standard 3G.
# iPhone 3.0 hits June 17th!
# Remote wipe command to delete data in case your phone is stolen or lost. iTunes will store deleted info in case you find it again. #wwdc
# Lost iPhone? Find it!
# Tethering = sharing intrawebs between iphone and comps (both mac and pc)
# Spotlight search. Also, rent and purchase movies, tv shows, music videos, and audiobooks. #wwdc
