Don't worry Spaz, EVERYONE knows. All you do is seek attention. No one needs to ask.
I'm pretty sure people can just be directed to...
Exhibit A
And this Gem of a thread. Exhibit B.
EDIT: To stay on topic, I use all the features. Thats why I bought it.
lol, exhibit B is golden. it should be stickied.
on topic; i don't have the 3gs yet, but on the 3g i have used mms and copy and paste (or rather, selecting for fast deleting).
the compass in maps, while i wouldn't use it all the time, would be very handy when in places i haven't been before. for example i went to manchester for the first time not too long back, i came out of the train station and had no idea which way to go. i tried to use gps while walking to get an idea of my orientation and which street to walk down (you can go left, right (ish, the road curves) or straight on). with the compass it would have been much easier as GPS wasn't accurate enough.
i'd also like the auto focus and video recording, can see myself using both fairly often. will also use bluetooth when i get my new car stereo.
