TapClockInfo will tell you your IP Address, Memory Usage, & Allow you to Respring right from your Lockscreen. You can tap your Lockscreen clock up to 3 times to change the Date info to something else. First your IP, then your Memory Usage, and finally an option, when tap & holding the clock, will respring your iDevice. Great feature to add and remember later at a time of need, go grab it, it's free!
