I have an iPhone.can't download apps?

I just got the 3G. It's unlocked and I can't download any apps! It'll either say "this app is not compatible with this iPhone" or it'll say something about the iOS version and how I need to update it. But I don't have any ios updates in my general section? What do I do? Shuld I take it to an apple store tmrw?

Intermittent Loss of Internet? (Two routers)?

I've been having trouble with both of the routers in my house for months now. The problem will come and go, but for the last few weeks it's been more common than any time before. I have two routers, our provider being Verizon FiOS. Both of them have an issue where between every 1 to ten minutes, usually averaging at about five, our connection will 'drop'.

It happens on every OS and every device. I'm running a 2011 iMac with bootcamped Windows 7, and Mountain Lion, as well as a 2007 and 2009 MacBook Pro. An Asus Netbook, two iPads, two iPhones, an XBox, and our TV service. All of them are affected by the problem, so I'm certain it isn't a hardware issue.

Every computer says we have full connection with the internet, either via Wireless or an ethernet cable, we've tried both on both routers. When we're watching TV and try to access the guide, we have a similar issue as the computers where it won't connect to the internet, and won't give us the schedules for TV shows, the channels, all that sort of thing.

I thought it might be an issue with the provider or the ONT, but we've had four or five technicians come in, one of the routers has been replaced three times, and no matter what gets done to the hardware nothing seems to fix it. We've tried everything bar replacing the ONT all together, but that's never really come up. I'm at my wit's end as far as fixing it myself or through Verizon is concerned, so I was hoping someone here might be able to give a bit of insight as to what's causing the problem.

Added (1). Sorry, I wasn't particularly clear. They each have their own connection, and their own respective IP addresses.

My IPhone froze and turned off and won't turn back on?

I was texting on my IPhone 4 when I looked away, and when I looked back, it was frozen on the lock screen. I let it sit for a couple of minutes, but then it turned itself off and I think it restarted because the Apple logo came up, but then it disappeared and I haven't seen any signs of life since. I had at least 75% battery, and I tried to reset it with the home+lock screen at least half a dozen times, but to no avail. If anyone can help, it would be greatly appreciated.

Added (1). I plugged it into my computer and opened ITunes, but it didn't recognize my phone being there.

Can apple tell if my iphone 5 has been jailbroken?

I have an iphone 5, software version 6.0.1. My volume down button is broken, and i have apple care. If i take it to the apple store to get a replacment phone, can they tell if it has been jailbroken even if i do a reset all settings restore? Thanks

Also, i've had a friend with applecare that had a broken lock button. He just took it in and they saw it was broken, gave him a new one on the spot. Is it being jailbroken before a restore even something i should worry about them finding?
