Signal is a new jailbreak app by Dev Team member PlanetBeing that lets map the cell towers your iPhone is connected to and displays detailed cellular information from the baseband. I can’t see much use for this app unless you’re the kind of guy who really wants to know where is cell phone signal is coming from.
The app is available in the Cydia Store for $4.99, which I think is a bit pricey for such an application. The good thing is you support PlanetBeing and keep it motivated to work on baseband-related stuff (ie. iPhone unlock).
If you download this app, please let us know what you think about it.
