Is intentional warranty claim illegal?

So i got an iphone and tried to mess around with it. I purposely make it defective and succeed in getting one exchanged using warranty provided. Is this act legal? And will it be unlawful if i continue doing this?

Why do I miss my ex but at the same time I hope I never hear from him again?

I don't understand why. A lot of times I feel like I don't want to hear from my ex because it can ruin my days sometimes. And other days I'm happy to hear from him and I miss him. Sometimes I think about how we used to talk to each other so much and watched things together and I get kind of sad because I don't have someone to do that with anymore. He's given me so many nicknames that I love a lot and no one calls me by them. He still calls me by one of them but that's it.

I feel like I really like one of the friends but at the same time I still like my ex a lot. And my ex says he liked two girls and sometimes he thinks about me so I guess that makes it three. I hate that I miss him randomly sometimes. A lot of times I just open up my iPhone notes and just type out whatever I want to say to him but I never send it. I get this feeling like once every two weeks, particularly on Sundays. Is there a way to stop it? We don't even text everyday, just whenever he texts or on the weekend which is just about 2-3 times a week.

I miss him but I don't want to tell him that.cause I think that's exactly how he wants me to feel. Because one of my friends likes me, he questioned a lot and he suddenly brought up some random girl he likes. I think he wants me to miss him and I do but I refuse to tell him. What should I do?

I've Jailbroken my iPhone now it won't work?

Okay. I installed a tweak to let me get free in-app purchases. I went onto the app store a bit later, however it wasn't working so I tried to restart my springboard. It worked, however I can't go onto my springboard. If I do, it just resets. I can't go into settings and the only way I can access an app is if a notification pops up and I tap it and unlock my phone. I tried to restore it (I saved a backup before jailbreaking it) , however I need to turn off Find My iPhone. I can't access it! I don't know what to do and I know Apple can't help me. Does anyone have any ideas?

My Phone:

White iPhone 4
iOS 7.1.2
Jailbroken w/ Pangu.

Why does my mac book not connect to my VPN?

I'm studying abroad in China and I have access to a VPN through my university in America. I'm able to connect to the VPN but it still will not let me get on Facebook, Google and other blocked sites in China. I use the same VPN for my iPhone and iPad and it works great. I have contacted my school but the IT guys were not too much help.
Is there any setting on my Macbook that would be causing this? Any ideas?

How to keep scammers away from bidding/buying on ebay?

I'm trying to sell an iPhone on eBay. Keep getting scammer bidding or buying the product and not paying for it. They keep asking me for my PayPal email address. I told them to pay it with the Pay Now button, then they never pay or respond. I keep having to open unpaid item case and keep having to relist the phone. How do I keep away these people, so legitimate buyers can bid on it?
