Cydia

Customizing the colors of your iPhone lockscreen time and date is simple, provided you have already jailbroken your device. A new tweak available on Cydia makes it possible to choose any color for the display, instead of the default white.

ColorClock can be found in Cydia under Sections -> Tweaks or by using the Search function. The tweak comes to us from developer Rudolph Lichtner for free. You can choose custom colors for the time and date separately using Settings.

The Transparency tweak from Cydia allows you to change your app icons by adding a new control panel in the Settings app. As you can see from the example below, the tweak's primary function is to turn your icons invisible. There is also a shadow option and a way to turn off the icon labels. I guess this will be a great tweak if they ever invent that transparent iPhone, otherwise this is just a fun and simple way for people to mess around with their icons.

Transparency is free from Cydia’s BigBoss repo. The tweak will automatically turn your icons invisible after it's downloaded and installed. Just open your Settings app and locate the Transparency panel to play around with the different looks, or to turn your icons back to normal.

Last Year's April Fool's joke reappeared in Cydia today, thanks to code that checked for the date and displayed a Twitter-inspired Quick Bar. Saurik explained that the prank was intended to emulate the discontinued Twitter iPhone app feature, which received poor reviews. The Quick Bar automatically displayed promoted tweets.

The feature was renamed the "dickbar" by some frustrated users before it was eventually removed by Twitter. Saurik realized that some people might get confused by the feature reappearing every April 1st, so he removed the code once and for all. Cydia 1.1.6 incorporates this change and can be updated using the Cydia app.

Locking the rotation with iOS comes in handy on the iPhone, preventing the orientation of the screen from changing unexpectedly when reading, for example. Accessing the rotation lock button from the home screen is simple, just bring up the multitasking dock by pressing the home button twice. Scroll from left to right and there's the orientation icon.

Apple has limited this feature to locking the orientation in portrait mode only, and the multitasking dock won't appear at all in the landscape orientation. Developer BTPankow has put an end to all this, releasing SwitcherLand to add horizontal orientation lock to the iPhone. This tweak makes it possible to bring up the multitasking dock even when using an app in landscape mode.

Zeppelin is a jailbreak tweak that allows you to change your carrier logo to different icons made by the jailbreaking community. Cydia is full of new logos and more and more are being added everyday. In fact, there are so many Zeppelin updates they're easy to miss. That's why the Zeppelin Super Set is great for Zeppelin junkies. The set offers the biggest collection of Zeppelin logos ever collected. There are over 230 Zeppelin icons to choose from, and hopefully more to come. It's a great alternative to downloading individual logos one at a time.

You can see from the small sampling above that the Zeppelin Super Set features sports teams, Angry Birds, clothing logos and much more. The set is available in Cydia via the ModMyi repo. It's free to download.

Those red numbered badges on the iPhone home screen can be helpful, indicating new text messages or unread emails. Sometimes they can be irritating, especially when there's no easy way to tell an app to stop nagging you with its badge. One example is the Apple firmware update, which will appear as a badge on Settings until you update iOS.

Jailbreakers know that updating iOS to the latest version isn't always a good idea if you're interested in keeping your Cydia apps and tweaks. Thankfully, developer John Heaton has created the BadgeClear tweak so that annoying icon badges can be easily wiped away. No options or settings are added to your iPhone by the tweak, just added functionality on the home screen.

Jailbreakers who feel like they're missing out on the new iOS 5.1 camera icon can now add their own with a new jailbreak tweak. Camera Grabber for iOS 5 adds the camera shortcut to your iPhone's Lock Screen without having to upgrade to iOS 5.1. This eliminates the need to double tap the Home button to quickly access your camera.

If you do not want the new icon but would like an easier way to access your camera, you can always install the free tweak known as CamFast. This tweak allows you to use Activator actions like "Double Tap" to achieve the same result as using the camera shortcut.

iMessage may make it simpler to communicate between iOS devices and an OS X computer, but there are many file types that can't be transferred using the service as they are unsupported by Apple. For those iPhone users with jailbroken devices, this is no longer a limitation.

SendAny and ReceiveAny are two complimentary iPhone tweaks that open up the doors of iMessage to any file type you care to send. These files can be sent to and from jailbroken iOS devices or between an IOS device and an OS X computer running iMessage beta. Not only this, but SendAny includes built-in DropBox support to send files directly to online storage.

The new jailbreak tweak AppUpdateNotifier ensures you will never miss another app update by sending you a notification when one is available. This seems like a decent tweak for people who use a lot of apps and are tired of missing updates.

The tweak sends notifications via Apple's built in notifications system even when your device is locked or asleep. You can set AppUpdateNotifier to check for updates hourly, daily, weekly or monthly, and you can even choose to ignore certain apps by placing them on the "Ignore List."

If you're looking for a way to simplify your home screen on demand, DockHide can be installed for free from the Cydia jailbreak app store. This tweak provides an easy way to hide the home screen dock, leaving only the icons and a clean, organized look.

Hiding the dock does not affect scrolling left to right, and you can bring the dock back to the home screen at any time with a simple gesture. Gestures to hide the dock can be configured through a simple Activator function, such as triple pressing the home button.
