Even though FaceTime works just fine over 3G or EDGE, Apple chose not to allow it. FaceTime is designed to work over wi-fi only. Apple chose it to ensure consistent call quality and also because carriers might hate to have so much load on bandwidth. So here’s a Cydia tweak to use FaceTime calls over 3G, EDGE or GPRS.
PowerUp is a free jailbreak tweak available on Cydia that enables additional options to you iOS device’s sleep button.
Normally you press the sleep button and then “slide to power off’” your iOS device. Wouldn’t it be nicer if you had more options than being limited to a simple OFF button? So here’s a simple tweak from Cydia that you can try.
PowerUp enables additional options on the menu screen when users try to put their iOS devices into off state. Earlier you were offered with a single option to turn off your device but now you can choose to select from three additional options of either reboot, respring or cancel the action.
There are also two different presentation styles for the power off dialogue and three different themes for action style sheets.
Some users may not find this to be useful but this is definitely a good tweak for those who want more options over a conventional menu.
