iPhone OS 3.1 beta now available for developer community

Update: Still tinkering, but we've seen a new "Save a Copy" option for 3G S video editing that lets you retain the original film while saving an edited clip (picture after the break, thanks Kevin), as well as some reports of MMS being activated, but it seems to stall before actually being sent out over AT&T's network.
[Thanks to everyone who sent this in!]














Hopefully this signals mms. But I don't think so. I installed the apn edit add on on my jailbroken iPhone and after entering stuff from help.benm.at I got mms to activate in the os but it would get an error before finishing the send. So this isn't that monumental
I don't understand why everyone is thinking this will "activate" MMS (its all over BGR too) - Ive got a 3GS (on O2 UK) and when I set it up the first thing I got was an MMS saying everything was set up, and I've since sent and received MMS pictures to my girlfriend.
So as far as I am aware - MMS is "activated?"
luke, people are referring to users on AT&T carrier in the US when they say they cannot use MMS.
One of my friends also reported that voice control on the 3GS will now allow you to speak into a bluetooth headset with 3.1, however the voice dial/multi function key will not activate the feature and you will still need to hold down the hold button for now.
email wynndc@yahoo.com if you need your UUID activated for 3.1 Thanks
iPhone 3.1 needs to have more bells and whistles to keep up with other smartphones..
