Accessing your iPhone filesystem directly with a command line console can be convenient and makes it possible to run utilities such as OpenSSH without the need to buy separate standalone clients. The MobileTerminal app has been around for some time and provides this functionality to jailbroken iPhone users. Unfortunately, the latest version of MobileTerminal available in Cydia crashes in iOS 4 and iOS 5.

The app is still available and easy to install, without having to manually decompress archives or copy files directly to your iPhone. The easy way to install MobileTerminal in iOS 4 or iOS 5 doesn't even require a computer. Follow these steps directly on your jailbroken iPhone to install a working copy of MobileTerminal:

The Steve Jobs biography written by Walter Isaacson is officially available for download from Amazon's Kindle store starting today. If you prefer to do your reading on paper, the 656-page book is also available in hardcover.

The authorized biography of Steve Jobs is based on hundreds of interviews conducted with family, friends, colleagues, adversaries and the Apple CEO himself. Although Jobs cooperated with Isaacson on the book, he did not exert any control over its direction, and did not request to read it before publication.

Developers are moving closer to an untethered iOS 5 jailbreak every day. Thanks to BigBoss, now you can protect your tethered iOS 5 jailbreak from making your iPhone unusable during a crash or unplanned reboot. The solution to the problem, known as a semi-tethered jailbreak makes it possible for the iPhone to come back up when you can't be near your computer for a full tethered boot.

There are some quirks to the SemiTether package, but having an iPhone that will start up is much better than one that just stays on the Apple logo. You'll still have to get back to your computer eventually to boot tethered for access to jailbreak apps and Cydia. Safari and Mail will also not be functioning when the iPhone is in a semi-tethered state.

Thanks to iPhone Dev-Team the redsn0w jailbreak tool is updated to jailbreak the iPhone 4 and iPhone 3GS running iOS 5. This is a work in progress designed to help app developers update their products for the latest firmware. As such, Dev-Team considers redsn0w a beta release and warns early adopters there may be lingering bugs in the firmware.

Before you go ahead and read the tutorial, be aware this does not apply to the iPhone 4S or iPad 2. Jailbreak solutions for these two devices are under development and have not been released. When it comes to the iPhone 4 and 3GS, most devices will require a tethered jailbreak.

Cinematographer Seamus McGarvey raised a lot of eyebrows when he told IFTN.com he used an iPhone to film some scenes for The Avengers.

“The beauty of photography or cinema is that you make every choice based on the content at hand. On The Avengers, I did a couple of shots on the iPhone and they are in the movie. In fact, they are in the trailer! I understand that sometimes there is no choice and you have to go for the cheapest option, but if you are limited for choice, you can still make poignant decisions that will effect the look of the film."

The Avengers is Marvel Studios most ambitious film to date, rumored to have cost over $200 million. The studio probably wasn't very happy when their director of photography told the world it was filmed on a cell phone. McGarvey later clarified he only shot one mobile phone POV using an iPhone.
