VibeTime tells you what time it is by vibrating your iPhone

  VibeTime is a tweak released last evening in Cydia, and with its help you can find out what time it is using the vibration system available in our iPhones. The tweak is made especially for those who don't want to take the phone out of their pocket to find out what time it is, and with the help of the Activator plugin and physical buttons you can force the iPhone's vibrating motor to tell you what time it is. Basically, from the Activator, you choose the tweak activation method, and when you execute the command, the iPhone will start to vibrate, each of the hour digits having a special vibration set.

Tell the time using phone vibrations. Have you ever wanted to be able to conveniently check the time without having to take the phone out of your pocket? For example, while watching a movie, sitting in a meeting, or in a social situation where it would be awkward for you to look away and check the time? VibeTime is the perfect app for this, as it allows you to check the current time while the phone is still in your pocket. Simply activate VibeTime by pressing the button combination (designated in Activator) and your phone will vibrate to time out. Each digit in the time is represented by a different vibration pattern. VibeTime must be set to an action in Activator in order for it to work. Look in Settings->VibeTime for more information about the vibration patterns.

  Of course, you have to learn those vibrations to figure out what numbers each of them represents, but we're talking about only 9 vibrations, so it shouldn't be that difficult. VibeTime it works only on iOS 5.x and only with iPhone terminals, and in Cydia you can find it in the BigBoss repo at the price of $1.99.
