The iPhone Dev Team has allegedly jailbroken the new iPhone firmware that ships with the recently released SDK (version 1.2, which will be apparently released to the public as 2.0). An user identified as King Chronic has obtained the firmware from his source simply known as "R" two days ago and the group managed to modify it to run applications not signed by Apple.

This doesn't mean that is is unlocked yet, the phone would still be locked on AT&T in the US and other networks elsewhere where it's available.

"Cheers to the Dev Team for the excellent job. Hopefully we can all have it unlocked & jailbroken iphone at the end of June. We've got enough time to do that & perhaps we can have it before the official Apple release for the new firmware..." wrote one user.

The Apple SDK ships with firmware 1.2, which can be run via an emulator. Firmware 2.0, with all the enterprise functionality, was only made available to corporate testers already installed on real iPhones. However, it appears it's the same firmware as 1.2, but the hacking community is tight lipped on this issue.

Meanwhile, today Apple announced that the iPhone SDK was downloaded already by 100,000 people. As you probably know already, the iPhone SDK provides developers with the same rich set of Application Programming Interfaces (APIs) and tools that Apple uses to create its native applications for iPhone and iPod touch.

The iPhone 2.0 beta release includes both the iPhone Software Development Kit (SDK) as well as new enterprise features such as support for Microsoft Exchange ActiveSync to provide secure, over-the-air push email, contacts and calendars as well as remote wipe, and the addition of Cisco IPsec VPN for encrypted access to private corporate networks.

On the other hand, Steve Jobs announced the AppStore, which is included in the iPhone 2.0 software. It is a new application that lets users browse, search, purchase and wirelessly download third party applications directly onto their iPhone or iPod touch. Practically, every developer can submit its applications to the AppStore; Apple would retain 30 percent of all sales revenues, too much some have claimed.
