iPhone Carrier Editor - No Jailbreak (iOS 6)

A common misunderstanding among iPhone owners is that Jailbreaking is required to achieve any type of customization. While this was mostly true in earlier versions of iOS, the 6th release (iOS 6) has a nice handful of tweaks. CarrierEditor is one of my favorites; it allows the ability to stop advertising for you carrier, and chose your own logo as a replacement. As you can see pictured below, my phone is on BatSignal.
