When connected to Wi-Fi, we roughly know whereabouts of where a particular hotspot is located, but with cellular data, things become a little more mysterious. We see masts scattered around, and we know when we're close to one, because we tend to get full signal strength, but in terms of which towers we're actually connected to at any given time, there's just no way of knowing. Although you'd struggle to find an app in the App Store to help paint a better picture of your cellular activity, the access to root files brought about by a jailbreak means Cydia developers can fill in these gaps, and a tweak by the name of Signal 2 will help you locate towers via map, find accurate cellular information and more.
