If you ever wanted to measure the speed at which you are travelling, then you will require this jailbreak tweak called ‚ÄúSpeed for Maps‚ÄĚ. This little utility allows you to figure out how fast you are travelling in miles or kilo meters per hour or feet per second.
While this cydia tweak is a bless for the bikers and boating guys, it may not be very useful for those travelling in cars. Note that this tweak will not add any icon. It will just a little circular icon that shows your speed inside Google Maps. Oh, and did we mention that it is free.
