iPhone OS 4.0 beta 2 and SDK released

Apple has released the next iPhone OS 4.0 beta SDK to the public, beta 2.  After releasing the first beta only two weeks ago - on April 8, this version comes fixes some known issues and added APIs for developers.

Developers upgrading from Beta 1 to Beta 2 should be cautious, as iTunes 9.1 does not support folder syncing, and users will need to uninstall Apple Mobile Device Support & Apple Application Support, before continuing.  Developers should also know that Apple has blocked access to the MobileMe features, so users won’t be able to locate, lock, display messages or remote wipe data.

Aside from the upgrade issues, Apple has fixed a number of display, error, and configuration issues with beta2.  This beta adds better support for the Mail.app, greater multitasking time completion, media player adjustments, and some issues with display bugs.

Hmm... Seems they broke the camera roll. Pictures and videos cannot be saved directly from the native Camera app. You can take pictures in other apps like Flickr and upload them, but you can't save pictures on your phone (including "Save Image").

I was hoping they would be a beta as well for the iPhone 2G. Oh well...

I think the iPhone 2G isn't going to get OS 4 at all.

Os 4.0 will be available for 2G, but multitasking will not be supported on 2G

It won't be available for the first iPhone and iPod touch.

Had a quick play with this. First thoughts:

Wallpaper option improved (it even lets you reinstall the "Bubble" background picture as it is now selectable) - It now shows a picture of the current wallpaper setup before you select the pictures.

Multitasking - Seems quicker to me, more "snappier" Switching between running apps now animates, moving the first app "behind" the second app. It looks quite nice.

Still some bugs. Saving pictures from Safari is very hit and miss for me, for instance.

Overall, an improvement so far for me, but clear that there is still a way to go before 4.0 is stable.

Oh, they have put a language change button on the keyboard also (similar to Microsoft Word - English (US) and English (UK) on my setup), making the "123" button smaller in the process.

That has been there for a long time now, at least as long ago as (almost) 2 years when I bought my 3G.

Really? It's the first time I've seen it on any of my devices (I've had each of the 'phone generations so far), including any of the 3.0 betas and 4.0 beta 1. Perhaps it has always been there as an option and never enabled it. It's just that I've seen it enabled as default. It's taking a little getting used to.

what does this means?
"greater multitasking time completion"

It means that the device won't close applications for you as quickly as it did before... since it closes them for you... right...

I think...

Anyone using the beta want to speculate on a release date?

June. If you've been following Apple for the last 3 years.

My bet too, along with the next iPhone.
