Chronic Dev has released its Mac version of greenpois0n, his 1-click jailbreak solution (see why you should jailbreak here). However, it will NOT unlock the device, enabling it to be used with different GSM carriers worldwide.

It is pretty easy to use and worked perfectly with my iPhone 4. Besides the tool, there’s a ‘Loader’ application that gets automatically installed on the iPhone after jailbreak, which gives you option to install Cydia.

You can also use Pwnage Tool by DevTeam to achieve the same. There’s practically no difference between the different tools, except for the fact that they come from different dev teams.

Here’s see how it works.

iPhone and iPod owners have been jailbreaking — or unlocking the operating system to run applications not approved by Apple — since at least 2007.

Why bother?

There are a number of reasons to consider jailbreaking your iDevice, whether it’s to create Wi-Fi hotspots with MyWi, get tweaks and added functionalities, many that weren’t previously available (multi-tasking, Bluetooth access, tethering), and the freedom to use third-party apps that haven’t been approved by Apple, whose family-friendly content restrictions have occasionally bordered on absurd.

Apple doesn’t like jailbreakers because of the loss of revenue and control over the devices, but the US Copyright office recently ruled that jailbreaking your Apple device does not violate the DMCA and is legal. Keep in mind that Apple still voids your warranty if you jailbreak, but now they can’t threaten to slap you with a $2,500 fine.

Cult of Mac has put together a Jailbreak Superguide to get you busted out and moving on.

If you’re getting around now to jailbreaking your iPhone and love social media, think about adding qTweeter to your app arsenal.

There are plenty of awesome Twitter and Facebook iPhone apps, but Cult of Mac finds qTweeter a must-have because you can broadcast social media updates just by pulling the app down from the status bar, and, say, vent about your co-worker while reading a particularly annoying email (not that we would, of course), rave about a new band you’re listening to the track or ask the peanut gallery what you should have for dinner by sending them a link to a take-out menu from a web page.

This $4.99 app has been one of our favorites since it launched in 2009.  Here’s Cult of Mac’s quick guide to getting you started with it.

If you haven’t upgraded to iOS4, VolumeButtonExtender available on Cydia is worth checking out.  While the iPhone offers a couple of ways to control your music, you need use the screen to do it, not a great solution if you’re jogging, using it in the car or otherwise need to turn adjust the volume or skip tracks quickly with just one hand and minimal attention.

VolumeButtonExtender gives you quick access to the music controls, even in standby mode, using just the volume buttons. Available on Cydia, the handy utility also helps extend your battery life. Here’s Cult of Mac’s guide to help get you started.

If you type a lot on your iPhone and haven’t upgraded to iOS4,  BTstack available on Cydia is worth checking out.

The iPhone’s on-screen keyboard and auto-correction are great, but if you write long missives or are used to hammering out complex messages on a keyboard, you’ve probably wanted to use an external keyboard to get your point across at one time or another.

This is where BTstack keyboard comes in: it’s a simple paid application that lets you hook up most external Bluetooth HID keyboards to your iPhone or iPod Touch. Keep in mind that it doesn’t support more sophisticated commands for your mobile opus (selection, copy/paste, etc.) but it works like a charm for straight typing. Here’s Cult of Mac’s quick guide to get you started.

Your life is on your iPhone, so if you want to share it with friends, family and co-workers, what’s better than capturing what’s on your iPhone screen? ScreenRecorder for iPhone is a Cydia application that captures your iPhone screen — be it a tutorial, demo or demonstration — with the tap of a finger. Here’s Cult of Mac’s step-by-step guide of how this paid app works.

Although the iPhone does allow you to setup a lockscreen passcode, it doesn’t give much flexibility in choosing one, allowing you to set only a four-digit passcode. If that doesn’t pass your security test, here’s how to set passcode your ex won’t be able to guess.  NB: If you haven’t upgraded to iOS4, this tutorial on setting up a lockscreen passcode is for you.

If you accidentally updated your jailbroken iPhone 3GS, you cannot simply downgrade it by restoring to an older version of the firmware (even in DFU mode) because of an added layer of security by Apple.

However, if you have a previously jailbroken iPhone 3GS, there’s a possibility that Cydia saved some files called SHSHs to help you bypass this added security. Cult of Mac’s how-to guide will help you do it.

The Backgrounder app makes running multiple apps on your iPhone easier than juggling your daily schedule. Do keep in mind that running too many apps will slow down your device and suck the life out of its battery a lot quicker.

Still, Backgrounder is a great gratis app we’re glad to have handy. Here’s Cult of Mac’s guide to how it works.
