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.
