BossPrefs is a very handy utility that i would recommend to everybody. I allows you to activate services separately. For example, you can enable WiFi, BleuTooth, Edge, etc by flipping a switch in the application. There have been a lot of updates to BossPrefs in the last couple of days. The most significant changes are that it’s now possible to hide applications right from the BossPrefs as it includes Poof! the application also adds another icon Power, This will let you easily reboot, respring and shutdown your iPhone or iPod Touch. All in all a must have app for your iPhone!
