updated – sites are saying the 3.0 Software Update will be released at 1am SG Time

Do note that as we are on the other side of the world from 1 Infinite Loop Cupertino, the iPhone OS 3.0 Software Update won’t show up on your iTunes today even though it was stated to be released on the 17th.

So let’s be calm, take a breather and sleep till tomorrow. Remember to update your iTunes to 8.2 and backup your iPhone data prior to updating.

In the mean time, here’s a graphical comparison of what you get from OS 3.0 between iPhone 3G and iPhone 3GS from Apple

The lack of Voice Control and Compass is also evident on iPod Touch running OS 3.0. The difference, according to John Gruber from Daring Fireball, is hardware related, rather than something that might be implemented via the OS update:

The compass app is based on a hardware magnetometer, and my somewhat-informed understanding of Voice Control is that it uses new digital signal processing hardware…by the way: video is a hardware feature of the 3G S camera, they’re not just snapping 30 frames per second from a still camera and using the CPU to stitch them together into video files

That said, it is still highly encouraged to upgrade to 3.0 to get the rest of the updates that come with 3.0. What’s more, its FREE! (at least for iPhone owners)
