iPhone 4s. Hubby has the new Samsung Galaxy III. Are you planning on getting something new? I got the iPhone last year because it helped to consolidate all the junk I was carrying but I could see going back to an android phone for a larger screen.
iPhone 5. But we also have an iPhone 4, HTC Evo and a iPhone 3GS in our house. I have used Blackberry, Palm and Android. I prefer the iPhone, however, I was pleased with the Android.
I'm not an Apple fan so I stick with android stuff. I have an HTC evo design 4g and my kindle fire which I rooted. Not going to upgrade to the new kindle fire since this works just fine for me.
