I have no idea, lol. I started with the original Motorola DROID but I went back and forth between android and Apple because I was having difficulties getting used to android, also back then every update sent my phone into a frenzy, then apple was easier but incredibly stifling and restrictive, finally several Android phones and several I phones later, I am finally comfortable enough with android and disgusted enough with Apple to stick with android. Pity it took me so long, though.
