It looks like Apple has already started sending out the beta version and SDK for the next iteration of the iPhone OS, 3.1, to developers.

The iPhone 3.0 software was released just about two weeks ago, ahead of the iPhone 3GS launch. By most accounts it’s pretty stable, though some users have been having battery issues. That’s why it’s a bit odd that Apple would iterate up to version 3.1 already, instead of something like 3.0.1, which it tends to do for minor updates and bug fixes. Could we be seeing a larger update to the OS already?

I’m told that there’s nothing much of interest in the release notes to indicate anything major that is new or changed.

I for one need the update, the no service problem is getting to be a drag.

Interesting isn't it. They're obviously aware things need tweaking. They were good with 2.0 as well, though, with getting those teething problems fixed. v2 ended up pretty incredible imho!

Speculation, also, that software 3.1 will not permit any Jailbreak or Unlocks that were developed for 3.0. So if you've used either just be careful before updating to 3.1

The news is coming out of what the new features are in iPhone firmware 3.1



A list of some of the new features found in the developer seed of iPhone OS 3.1 has been compiled by the iPhone Blog.

Currently known changes:
- Non-destructive video editing now gives you the option to trim your clip then “Save as copy…” rather then replacing the original clip.
- Voice Control now works over Bluetooth
- iPhone vibrates when moving icons
- Updated AT&T profile to 4.2
- Updated modem firmware to 5.08.01
- Improvements to OpenGL and Quartz.
- APIs to allow third party apps to access videos and edit them.

No mention of whether or not the 3.0 Jailbreak/Unlock will work on 3.1 yet. In this respect there is a salutory warning from The Dev Team ...


The iPhone Dev-Team has asked 3GS owners to prepare for the upcoming jailbreak by capturing their iBEC and iBSS files.

-----
Remember we warned you to stay away from any updates to 3.1 if you want to be able to jailbreak or unlock your 3GS.

Well this is an additional message to all you 3GS owners that would like to jailbreak your device sometime soon, but this advice comes with a warning! A warning that if you accidentally upgrade to 3.1, you will not be able to use Ultransn0w, so please re-read and double check this warning at the bottom of this post before proceeding.

You may have read or heard about techniques to capture files during the iTunes restore process. These will be required to jailbreak your phone in the near future, most of the methods involve icky USB snoops. Well, there is an even better and more reliable method to get your hands on those lovely files.

During the restore process iTunes nicely keeps these oh-so-top-secret-files in a lovely accessible place for us to copy out and backup, that place? /tmp on Mac OS X or %TEMP% on Windows. Thanks Apple — handy!

The downside to this approach is that you actually need to go through the restore process to get these signed files, which has risks if you are anywhere near 3.1 or 3.1 beta :-)

If you are ready to proceed and you know the risks we’ll get down to the nitty-gritty -

So during a usual recovery with iTunes, your signed iBEC is written to /tmp and during a DFU mode restore the signed iBSS is written there also. To be sure, restore in both modes one after another to be able to grab them both. You’ll need to keep an eye on the temp directory and copy it before it is deleted again by iTunes. I’m sure some nice folks will create a tutorial about this, we’ll link to the first person who makes a good one.

Should you choose to accept this mission, act fast, this needs to be done quickly! But again, always, always double check here to see if 3.1 has been released, if is has, then don’t do this.
