I am always forgetting my prepaid numbers esp when i’m in a city for a few days, so i just snap the number on my iPhone camera and make it my wallpaper, so it’s easier to get at whenever i meet someone who needs it. (i know it’s a bit blurry but at least it’s mostly legible)…
Seems like you could do this with 90% of GSM phones out there.
Hell, why does it have to be just your prepaid number? I could keep other things as well, like lotto numbers, social security numbers, other’s credit cards, license plates. All sorts of numbers, that i may forget.
At that point, why must it be numbers? Could you do names, and addresses as well?
What about images, and song names. See a song on the radio you like? Take a picture of the song name, so you can download it later.
