I used my 4s until it literally became unusable due to the satellite sync issue. Still got it here, one day I shall get around to jailbreaking it and turning it into the music player for the garage.

(the last phone I bought was literally a Nokia 3310. I just take everyone's hand me downs when they upgrade through plans, I don't give a shit. It's a phone. It makes calls.)
