iPhone 3GS

After selling a record 7.4 million iPhones last quarter, Apple is setting up to meet high demand during the holiday season. Inventories have been low in many countries as the iPhone 3GS has been flying off the shelves.

Apple will also be selling the iPhone on several new carriers in the coming months which could further reduce supplies. Carriers that will carry the iPhone as early as next month include Orange and Vodafone in the UK, Telus and Bell in Canada, and China Unicom.

The latest version of the blackra1n jailbreak has hit the streets. RC2 will even jailbreak brand new iPhone 3GS models running 3.1.2 from the factory with a "tethered jailbreak."

This means when restarting your jailbroken iPhone the device must remain connected to your computer to properly boot. Apple thwarted the “24kpwn” exploit used by Geohot and iPhone Dev-Team in the latest firmware release on new iPhone 3GS models, making the tethered jailbreak method necessary.

The latest and greatest jailbreak tool has been released and it supports iPhone OS 3.1 on the 3GS hardware. Before you get too excited, keep in mind it will only work if you've already jailbroken your iPhone 3GS when it was running 3.0 or 3.0.1 firmware.

Turns out if you've installed an update directly from Apple using iTunes on your iPhone 3GS or the device came pre-installed with firmware 3.1 then you're out of luck. PwnageTool 3.1.3 is only available on the Mac platform. Dev-Team has stated it has no intention of developing a windows version of this particular tool.

The latest firmware update released by Apple may have improved security and added features, but some iPhone owners are having problems. Reports from users on the Apple support forums indicate a major problem with updating to iPhone OS 3.1 on the iPhone 3G.

Users are ending up with bricked phones, and iPhones that crash several times, requiring a hard reboot. Holding the sleep and home button doesn't always work, however. Some users are finding it necessary to downgrade to iTunes 8 and firmware 3.0.1 to solve the problems.

Surprise! The popular iPhone app Yelp has a secret feature that overlays nearby points of interest on live video of your surroundings. This augmented reality feature is available in Yelp version 3.0.0 on iPhone 3GS.

To turn on the feature, called Monocle, make sure "Location Services" are ON. Launch Yelp and select the "Nearby" screen from the bottom menu. Now gently twist or shake the iPhone a few times until the dialog box stating "The Monocle is activated" appears.
