Apple fixed almost every gripe I've ever had with my iPhone in the 3.0 release of the OS.
- Full bluetooth - stereo headphones work in iTunes, file transfer, contacts transfer
- MMS - send and receive pictures. this took embarrassingly long, but is finally there
- cut and paste - apparently you can also shake the phone to undo/redo
- landscape mode - text messages and emails work in landscape mode, same as Safari already did
- spotlight - search the phone for anything
- no multitasking, but push notification - unread email counts and other app information can update in the background, but can't run in the background. apparently backgrounding kills battery life.
- a tethering client (but AT&T isn't yet onboard with tethering).
- Turn by turn on GPS apps, but not in Google Maps due to licensing restrictions.
- calendar update, support for CalDAV
- new stock app, but bloomberg's free app already had that base covered.
- voice memos. like a personal audio recorder.
On the minus side, my first-generation phone doesn't get the updates to MMS and bluetooth, which are the big two for me.
I'm debating buying a new phone the next time they upgrade the hardware (my contract still has six months left). Any idea when the next upgrade is supposed to go through?
