Upgrading phones

Hubby and I are thinking about getting iPhones in a few months when we are eligible for upgrades. I'm excited to try out stuff that they have on them that we don't get on our phones. There's just a lot more apps and stuff for iPhones. They even have card reader things, like a mobile Retail POS System, that just snap in and can read credit cards. Not that I need something like that lol, but it's pretty cool. Plus they have better quality camera and bigger screen than my current phone. My only worry is that everyone I know with an iPhone has the screen break at some point. With how much my phone gets dropped and mauled by children, I worry about it getting broken really quick. I will definitely get some kind of protective cover.
