Signal 2 is a Cydia tweak developed by Planetbeing, who is a member of the Evad3rs which brought us the iOS 6.x Untethered Jailbreak. What the tweak does is relay information regarding cell towers your iPhone is connected to as well as other cell towers in the area and displays their locations on a map. This allows you to get an idea of how well your coverage is and where to go to get the best reception.
Combined with the free iPhone carrier unlock (UltraSn0w) that planetbeing has helped create, users can swap SIMs and determine which carrier is best for him or her based on cellular coverage. In addition the map, other useful technical data is displayed including RSCP (signal strength) in dBm and Ec/N0 (signal quality) to all neighbours, the PSC of the cells, as well as the frequency each cell is broadcasting in.
Signal 2 is definitely an interesting Cydia tweak, that seems more like a novelty tweak than anything to me, considering most people don’t have unlocked devices, so they can’t just pop in any SIM Card they wish. Regardless, there is arguably a lot of functionality in this tweak and if you are interested you can find it in the ModMyi repo for a price of $3.99.

That’s pretty cool. Might tell me how good my reception is in some areas.
Sadly, it doesn’t seem to work. If I tap the “Signal” icon, the screen flickers and comes back to exactly where it was. The screens shown in the Cydia listing don’t appear.
Does it matter that I’m in England? I wouldn’t expect it to, and the app doesn’t say anything about being restricted in where it will work.
can they make one for verizon users :D
Mine does the exact same thing KeithJ does. So far $3.99 wasted. I emailed support with no response yet.
It’s possible it doesn’t work outside the US..I’m in the US and bought it yesterday and it works exactly as described. Pretty cool. $1 or $2 probably would have been a better price, but since the author was planetbeing I didn’t mind a little extra support.
Update: after emailing the developer the problem was fixed and the app does exactly what it says it will do. Best $3.99 I’ve ever spent. I would highly recommend this. I’m on Verizon and it’s working great.
bought the app. Wish it could use the more accurate google maps
Novelty that seems to place cell towers in places that I can find no evidence a tower exists. Tower placement conflicts with OpenSignal in terms of tower direction.
It might be placing towers at some type of area centroid rather than a hard lat/Lon. Just a guess. Regardless, I don’t trust its tower maps.
Don’t waste your money. I did and I feel ripped off.
or you’re connected to a sting ray device
Doesn’t matter why, it’s not accurate so why bother? However, it was never accurate and I have a hard time believing the government has installed thousands of such devices everywhere.
