HeadphoneLauncher is a new tweak that allows you to view and launch apps from the Lock Screen. The tweak launches the selected apps every time your headphones are plugged into your iPhone. You can choose and rearrange the order that the apps appear by using the Headphone Launcher panel under Settings.

HeadphoneLauncher will also display the media controls on your Lock Screen. This is a great tweak for people who like to listen to music while walking. Unfortunately, it doesn't seem to work with Siri Board which would've been a nice bonus.

Ever send a message with invisible ink to a friend? Now with the Black SMS app, text messages can be encrypted and decrypted easily by any iPhone owner with the right password. Once Black SMS is installed on your iPhone, the secret message is simply typed into the app and a password assigned.

Black SMS uses Advanced Encryption Standard for serious security, even though the app is simple to use and only costs $0.99 in the App Store.

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.
