Want a number indicator for cellular reception instead of bars? Read this — and no jailbreak required!
My good friend Mat texted me today and asked me this question. Of course, I said yes, and now my status bar looks like what you see above. Want to know how? Read on.
Step 1: call *3001#12345#* (a menu will show up)
Step 2: Press and hold the lock button until the 'slide to power off' option appears. Press and hold the home button until you return to the home screen. Viola!
You can tap the numbers to return to the bars, and vice versa.
The closer the number to 0 (you'll probably never see it that low though), the better the reception.
If you want to get rid of the numbers, simply dial the number again and hit the home button.
