iPhone 3GS

Just when you thought you didn't need anything else for your iPhone 3GS, along comes Zacuto with the must-have video accessory of the century. Behold, the ZGrip iPhone PRO.

This professional grade videographer pistol grip secures the iPhone 3GS and provides a firm, stable platform for shooting hours of video. An optional tripod attachment is compatible with the ZGrip iPhone PRO and allows you to hook the entire setup to your own tripod.

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.

AT&T does not currently allow tethering on the iPhone even though Apple's iPhone OS 3.0 includes the feature. The company is still deciding what a tethering data plan for iPhone would cost and how it would be structured.

Tired of waiting? If you have an iPhone 3G or 3GS running OS 3.0 and a computer running iTunes 8.2 on Mac OS X here's how to activate tethering. You will be able to connect your computer to the AT&T data network using USB or Bluetooth via your iPhone.

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.
