Some of the best jailbreak tweaks only do one thing. Simplicity is the word to describe NoSTUArrow, which removes the off-center Slide to Unlock arrow from the iOS 7 lock screen. There are other ways to achieve this effect, however NoSTUArrow makes it easy.

Eliminating the arrow from the left side of the Slide to Unlock text happens immediately after NoSTUArrow is installed. The tweak can be found on Cydia for free, and has no options or settings to configure. Once the arrow, which looks like a mathematical "greater-than" sign, is removed the iOS 7 lock screen looks even cleaner.

Getting now playing info from anywhere on the iPhone home screen is the goal of the new jailbreak tweak #PlayMe. For those who use any number of music apps, getting the current track name in iOS 7 means navigating to the app or pulling up the Control Center. Now these extra steps can be avoided.

Installing #PlayMe from Cydia results in now playing information being added directly to the iOS status bar. This means that while a track is playing, the song title and artist will cycle in the status bar. Adding this info to the lock screen and home screen provides a convenient way to see what's playing without much hassle.

Vine users can now send video or text messages to anyone listed in their Contacts app, or to other Vine members. To send messages via the Vine app, just select the “Messages” option in the Settings menu or tap the Message button on a person's profile.

The new "VM" feature only offers the ability to start one-to-one conversations, not group chats. However, you can send as many video messages as you want, you just have to start separate conversations with each contact. Like Facebook, VM also includes two inbox options: The first option is for people you know, and the other is for "people outside your network". You can disable the option to receive messages from strangers by turning off the "Other Inbox" feature in your Settings menu.

The slaycation levels also up the ante by adding a second Beach Princess for players to protect, and introduce the new Hasselhoff Lifeguard and Galaxy Soldier heroes.

Castle Doombad is one of the best games released for mobile devices this year.
