iPhone 3.0

Car sharing using your iPhone has never been easier. The free Zipcar iPhone application has a multitude of features that make finding and renting a car incredibly convenient. There's even a virtual key fob.

Yes, you can lock and unlock the car and even set off the panic alarm using your iPhone. All you need to do first is scan your Zipcard when the car reservation begins.

This Friday AT&T is expected to text its iPhone customers in groups every hour, notifying them that MMS is finally ready for action on their iPhone. Some reports have indicated this process could start as early as 10AM Eastern Time.

MMS will be activated by a carrier settings update from iTunes. The service will make it possible to send photos and videos along with text to other mobile devices without using email. MMS will not be supported on the original (2G) iPhone.

You may be aware that Microsoft's Zune HD will hit shelves on September 15th. The portable device will play HD video and compete with Apple's iPod Touch. What you may not know is that the iPhone 3GS is already capable of playing 720p and 1080p resolution HD video without skipping a beat.

Although the iPhone screen resolution is only 480x320 pixels, the possibility of future Apple devices linking to external displays for HD video playback is real.

Looking for a new, unlocked iPhone that hasn't been hacked? Normally iPhones come locked to a carrier, such as AT&T, and must be modified to allow usage with other networks. This could violate terms of service and Apple's warranty rules.

Two iPhone models that have never been locked can now be found for sale on the website Buy.com. These legally unlocked iPhones should be fully covered by Apple's warranty and make it possible to use the device on many GSM networks with no contract.

Now iPhone 3GS users have two jailbreaking solutions at their fingertips. Shortly after geohot (George Hotz) released his own jailbreak in the form of purplera1n, the Dev-Team released a new version of redsn0w for the iPhone 3GS.

As we previously reported here, geohot recommended that everyone with a 3GS follow specific steps to preserve their future ability to jailbreak. Turns out he wasn't content to wait for Dev-Team to release redsn0w for the 3GS.

Finally, the iPhone 3GS digital compass is getting a workout. Software developer acrossair has submitted the first augmented reality application to the Apple AppStore for approval. The app is called Nearest Tube, and will help Londoners plan routes and find the closest underground station. What's unique about this process is how the app delivers information.

Instead of a static map, Nearest Tube displays subway information in real-time, overlaid in 3D on top of live video of the user's surroundings. Holding the iPhone 3GS horizontal will show arrows pointing to different train stops, and tilting the device upwards will overlay signs in the direction of different stops. These signs look like a heads-up-display, and give more information about how far away the station is and what lines connect there.

iPhone blogger George Hotz has discovered a new layer of security in the recently released iPhone 3GS. If you're waiting on iPhone Dev-Team to release a jailbreaking and/or unlocking solution for your iPhone 3GS, generating a unique certificate for your device could keep your options open.

Apple will likely release iPhone OS 3.0.1 soon, possibly postponing a jailbreak even longer. George Hotz explains the process of generating a certificate below.

Apple sold over one million iPhone 3GS units in three days. Of course there are bound to be some problems. Reports are starting to come in of some issues and bugs.

The problem pictured above is a white iPhone 3GS that has overheated. The abnormally high levels of heat have discolored the white plastic on the back of the iPhone so that it appears pink.

But wait, there's more! There are still some details about the iPhone 3G S that were not announced at the WWDC keynote speech. In fact, we're betting that even more information will be revealed when the new model actually hits the streets on June 19th.

Apple did not mention the specifications of new hardware in the iPhone 3G S on Monday. Turns out a T-Mobile site in the Netherlands has verified that the RAM has been doubled to 256 MB.

During the keynote address at WWDC 2009 Phil Schiller, the senior vice president of Apple's worldwide product marketing, revealed the new iPhone 3GS. The new iPhone model has the same design as the iPhone 3G, however the S stands for speed.

The new model will be faster and have a higher storage capacity. Apple also announced that an 8GB version of the iPhone 3G will sell for $99.
