My iPhone has three problems: 1. It crashes. They are mini-crashes usually, where it abruptly stops working and closes the open app, as if I had pressed the home button. This could be a mechanical problem with the home button, because it happens in all the apps if I use them long enough. 2. Sometimes a webpage displays, but the buttons ABSOLUTELY don't work. Nothing highlights if I hold my finger on it (as is normal) and nothing clicks. The browser buttons work, just not hyperlinks, and boxes won't accept text - as if the whole page was just an image. 3. Sometimes it thinks the headset is plugged in, and mutes its speaker accordingly, but the headset isn't plugged in. Anyone else experience these things? Any specific suggestions? Any general suggestions? Thanks.
