Despite iPhone 3.0's push notifications and previously mentioned Google Sync's contacts and calendars syncing chops, push Gmail still hasn't come to the iPhone. But with the Prowl iPhone application, you can now push Gmail notifications—and then some—to your iPhone.

iPhone/iPod touch only: Remember previously mentioned RunPee.com, the ingenious website that tells you when to head out for a bathroom break during a movie so you don't miss any good parts? Now the site has released its first mobile version for iPhone users.

Remember the Milk just got a lot more helpful on your iPhone. Version 1.1.1, now available, adds push notification powers to the task management app, giving you a heads up when your important to-dos are coming right up.

Mac OS X only: If you're running a 2G or 3G iPhone with the 3.0 firmware, your (unofficial) carrier options just opened up a bit, as the Dev Team has delivered Ultrasn0w 3.0 for full unlocking.

Mac OS X only: The iPhone Dev Team has already released the iPhone 3.0-jailbreaking Pwnage Tool for Mac OS X (just two days after the iPhone 3.0 release), with QuickPwn for Windows and OS X soon to follow. There are a few catches, though.

Expect a glut of media coverage as the iPhone 3GS goes on sale in the US this weekend -- but in Australia, we have to wait until Friday June 26 for the third major model of Apple's phone to appear. What do we know about what will happen when it does?

iPhone/iPod touch: Evernote, the brain-expanding memory and note tool, is making full use of the iPhone 3.0 features with a new version that makes reading, synchronising, mapping, recording, photo-capturing and landscape-viewing your notes easier, and promises app interactivity to come.

Optus has finally announced its plans for iPhone tethering, and they're not pretty: if you want to use your iPhone running the 3.0 OS as a modem, you'll have to pay an extra $9.99 a month for the privilege.

The iPhone 3.0 software update hit servers a few hours ago, and we spent some time playing with every new feature we could find. Step inside for a look at our favourite new iPhone 3.0 features.

Australian users who have managed to get iPhone 3.0 installed are reporting on Twitter and forums that the MMS features are working with all the major carriers (so clearly I got that wrong), but note that Optus is indeed blocking tethering, saying this has to be enabled (and charged for) before it works. How's 3.0 working for you? Share in the comments.

Plug in your iPhone and smash the Update button in iTunes to grab yourself the latest and greatest update to iPhone 3.0, complete with copy-and-paste, MMS, search, push notifications, and more.

If you can't wait until iPhone 3.0 gets its official release, Whirlpool's collected the files you need to make MMS work on an Australian iPhone.

We haven't verified any of these methods yet (as we don't have access to iPhone 3.0), but word on the street is that iPhone internet connection sharing—aka tethering—is already working on the iPhone 3.0. Our gadget-loving sibling site Gizmodo has a detailed guide to enabling 3G tethering—but they haven't verified it either. According to Mac Rumours, USB tethering is also working. On Tuesday Apple indicated that tethering would be an option in the 3.0 software update, but that it's up to the providers to allow it. So while this really isn't available to the majority of us yet, it's a good sign of things to come. We particularly like the notion of USB tethering, which would likely mean less of a battery drain and better connection.

How to Enable 3G Tethering in Your iPhone 3.0 Now

Apple's releasing some hot new features in iPhone 3.0 mid-year, but will it be better than Google's Android? Let's take a look.

One of the features Lifehacker US singled out straight away as appealing in the forthcoming iPhone 3.0 release (apart from the finally-here copy and paste option) was the ability to send and receive MMS messages. Photo frenzy ahoy! However, there's a disturbing note at the foot of Apple's official press release:

MMS may not be available in all areas.

iPhone 3.0 won't be on general release until mid-year, which means there's plenty of time for a local telco to get on the MMS bandwagon if they can see a potential revenue source. On the other hand, there's a precedent for it not happening: visual voicemail, one of the most hyped features of the original iPhone, never made it down under. If I was a betting man, I'd be inclined to back the "no MMS for Aussies" horse.

The iPhone event just ended, and the upcoming iPhone 3.0 software update adds a ton of new functionality to the iPhone—claiming over 100 new features, including long-awaited copy and paste, MMS messaging, and more.
