We've got two big bits of news lined up today for the guys keen on developing their own software on the Apple iPhone. The first matter we're reporting is that a new version of the iPhone's 2.0 Beta firmware (aka firmware 1.2) has been released.

This new build, dubbed version 5A240d, will carry updates focused on Exchange support (according to MacRumors). In line with this news, Apple's also released  iPhone SDK Beta 3. We advice the users to clear some room - if the Beta 2 SDK's release indicates anything, it's going to require a ton of space on your hard drive.

We also remind the readers that the iPhone firmware 2.0's public release is currently set for the month of June, at about the same time as Apple's Worldwide Developers Conference 2008. Drop by again in case we run into any more updates. The download for the iPhone's SDK Beta 3 is available via the source link below.
