I don't know if I should call it freezing but sometimes when I press an icon they don't work. I have to hit the home button or hit the button up top to turn it off then back on. Anyone else having this problem? I
I'm sure each and everyone of us has encountered a slight freeze, maybe not as harsh as whats happening to yourself justinss. Is your device jailbroken, as this maybe a factor of your phone laggin or not responding. If it continues try a restore as a last resort. If that doesn't sort it then i suggest you head towards your carrier or an Apple shop and seek a new iPhone.
I've had no such thing - quite the opposite, really. As soon as I tap an icon, there's the app in front of me. So, is this just one app, or multiple ones? If it's just one.. bad app. If it's multiple ones, try what was suggested above, and then a restore in iTunes.
I think a soft reset is the same as a reboot. Hold the home and the sleep awake button until it goes past the slide to turn the phone off. Hold until you see the Apple logo then release. Not sure about a hard reset. haven't used an iPhone till this week and it had been over a year and a half since i owned one.
