In iOS 7 there was a way to get the signal bubbles in the top left corner to go to a number. I had this on my iPhone 4 on iOS 7, but can't get It to work on my iPhone 5c on iOS 7.1.
After shutting down the phone and turning it back on it seems to come back with just the regular iOS 7 signal dots.go into your phone app, type in "*3001#12345#* and tap call
it'll bring you to the field test app
hold the power button and shut down your device
when you turn your device back on, it'll be the signal numbers
if you ever want to return it to normal, just go into the phone app, enter those numbers and tap call again. it'll bring you to the field test app, just press your home button and everything will revert back to normal
note: this can also be performed on a non-jailbroken device!

Seems like if you restart (hold lock and home button together for about 5-10 seconds until the phone restarts) rather than shut down (holding just the lock button and using the power off slider) then it works.
Yeah tried that after the shutdown. For some reason only the restart got it to stay.Yes, that works too. Although I'm not sure why a normal shut down and reboot didn't work for you
Did you try tapping the signal bars? That will toggle between the signal number and signal dots (but the default will be signal numbers)
Yup, resetting (holding the sleep and home buttons together) seems to do the trick. Shutting down (holding the sleep button and then using the power off slider) and then turning the phone back on, doesn't seem to, at least not for me.
