Help! I think my phone is jailbroken(?)
I was looking up cool things to do on iPhones and there was an ad that popped up it said "Get cool apps for your iDevice!" so I clicked it. I always charge my phone on my laptop because it doesn't work in the wall. Anyway, as soon as I clicked the link it started downloading something and I clicked cancel but it opened anyway. Then all of a sudden my phone rebooted and all my apps were missing except for the ones I installed from the app store. Only a few apps that came with my phone were there. One app was new it said "Webapp1" and the app picture is just white. I am so scared. I looked up what the things that were wrong with my device and it says something about it being jailbroken. What does this mean? It said I can fix it by restoring my device. I tried this and it's still the same. I tried everything. I don't even know what jailbroken means. A thread on the apple website said that my phone is going to be broken forever unless I buy a new one! It said it's not covered by Apple because I messed it up. I don't know what I did and my family can't afford to buy me a new phone. We don't have much money to begin with. I honestly meant no harm to my phone. I was actually about to put my phone in airplane mode because the website I was originally on said it helps it charge faster. I shouldn't have clicked on the ad. I've been crying for about 1 and 1/2 hours and my mom keeps asking me what's wrong but I just say I stubbed my toe. My grandfather bought me this phone and he already had to put out money twice because I dropped it. I just keep hitting myself because I'm so stupid. PLEASE HELP ME. Anyone. Just tell me:
1. What does jailbroken mean?
2. How do I fix it?
3. Is it covered by warranty?
