Can anyone tell me what I need to do to fix it? I have tried just about everything.rebooting it and resetting network settings and nothing seems to work… Please help.

Portable Wireless Motion Sensors?

My friend has me watch his house quite frequently when he goes out of town and I often stay at his house for him to watch it as well. Most of the day I'm busy working and running errands and I was wondering if there's some type of system where I can setup portable wireless motion sensors and/or security cameras around the house that can alert my iPhone or send me an email or text if there's any activity? His house does not have an alarm system and is not in the greatest area of town so I was wondering about this. Any ideas?

How to unlock a Sprint iPhone 4S?

I want to be able to use it with other carriers, but I'm not sure how. I have heard of using the GPP sim but I'm afraid that if I update it, the phone will re-lock and I would have to purchase another GPP sim. I've looked up other methods of unlocking a Sprint iPhone 4S, but they're terribly expensive - around 100 dollars!

Does anyone know any way to unlock it for a cheap price, or even free? Any help is appreciated. Thank you!

How to sync music from iphone to new itunes without losing all the music I have?

I just got the new iTunes 11 on my windows 8 computer and I'm trying to figure out how to sync my iPhone 5. I have done all the stupid stuff the other websites have said, Authorize your computer (done), go to preferences and change to prevent ipods, iphones, and ipads from syncing automatically (done), and I even read some stupid thing about getting music from my old computer with a flash drive. I would have done that if I had my old computer, but I don't. Every time I click sync music it tells me I'm going to erase all my old music. I really don't want to do that. Help!

Added (1). Emmie196, I've tried backing it up and still nothing has shown up, should I go through with that whole erasing crap if I've backed it up? I'm usually good with this sort of stuff but I can't figure it out and it's really making me mad!

How loud does a sound have to be to break stuff?

Let's say we're trying to break a glass wine under 30 seconds with pure sound. Let's also assume that the sound we're emitting perfectly matches the glass's frequency (resonance). Approximately, how loud should the sound be in db? Maybe 100?

Another question: Do small, handheld electronics like iPhone or Nintendo 3DS break easily from sound like glass does?

Could I bring the theif to the police?

This has happened twice this month to me. Around the first of the month Chase called me and told me about possible credit card fraud and it was fraud. The person bought a iPhone online and they said they might have changed their IP:-<

I didn't have to pay anything since i didn't buy so i didn't really care.

It happened again! Yesterday! Some person bought $50 worth of gas!

I asked the Chase person if they would catch them and they said they wouldn't be looking for them but the police would but i probably shouldn't worry about it because they never catch most people!

I search my credit card info on google to see what came up because i have used this card in over a year. My info came up! My name and address! It was on a site called Hack Credit Cards 2013 or something like that and it had my info and like 100 other peoples.

He was at a gas station! I'm sure it had cameras!

Thats why i'm wondering what's the chance of the police going to find this guy or these guys. I don't want anyone to have my info and then maybe come and kill me. OR could I tract down these guys myself like the movie Identity Thief and bring them to them?
