Jailbreak or downgrade without a computer?

I have no computer. Just an iPhone 4 or 5 (don't know which as it was a gift). I want to jailbreak it but since it has iOS 6.1.3 I can't. How do I downgrade to iOS 6.1.2 so I can jailbreak it. Keep in mind I do not have a computer.

Hobbit: Kingdoms of Middle-earth Free Mithril?

I wanted to ask if there's any way to get more Mithril for the iphone and android app "The Hobbit: Kingdoms of Middle Earth". You need it for nearly everything and I wanted to know if there's a way to get it for free.

Problem with iPhone 4 after installing iOS 7?

Some time ago i downloaded the uTorrent iOS 7 for my iPhone 4 (I know it is illegal, and I know it would be a risk - maybe my phone would break down or something like that, so pointing out it was stupid I downloaded the uTorrent version is pointless now) and one night i woke up by the light on my phone.

I looked at it and the screen was all white with a black apple (it has always been black with a white apple) and after a while my lock screen showed up. I tried to unlock my phone but instead of unlocking it, a grey box turned up around the "slide to unlock" and then a voice read out loud what was in the box (so the voice said "slide to unlock"). Then i touched on the clock and again - a grey box around the numbers and a voice saying the time.So, basically everywhere i touched a grey box around the area i touched would appear and a voice reading what it says, it even said how much battery was still left and the name of my Wi-Fi.

I later figured out that if i clicked twice quickly at the "slide to unlocked" the phone got unlocked and it showed me that i should plug the phone to my iTunes. I did it, but nothing happened. My phone couldn't synchronize as it always could (even after I updated to iOS 7), and on my phone appeared a white background with a small black text saying: Your phone isn't activated, please download the newest version of iTunes and plug it in again.

The problem is now that I already have the newest iTunes, and still nothing happens. I can't do anything with my phone… I can't even restore it or downgrade it or anything else…

I really want to know if someone else has had the same problem with their iPhone? Or maybe some of you know what I should do? I was thinking of taking it to the store where i bought it, but since it isn't running the original iOS it should run, they will not/can't do anything about it… (And sorry if there's some misspellings, I'm from Denmark, so it isn't the best english, but I hope you understand my problem!)

Lifeproof Frē iPhone 5 Case end call button & Siri not working?

I purchased my Lifeproof case in November of 2012. Since then I have had to call Lifeproof customer service several times and have had my case replaced three times. Last week, the case started acting up yet again. Whenever I try to hang up phone calls, nothing happens, so I need to press the power button or open the charging port and press the button to end calls. Also, Siri doesn't work well anymore. I can open Siri fine by holding down the home button, but when I try to tap the button to close it, the phone makes the Siri noise, but the screen just flashes black a couple of times, and Siri remains open. All the problems I'm having are centered around the bottom of the screen. Not to mention the annoying little oil marks and bubbles all over the screen. What should I do about this case?

I can't put gifs on my iphone?

I made a gif on my pc and made a folder for the pictures I want synced to my iphone, connected it to iTunes, and put the gif in my phone's photos. But when I go to my photos on my iphone The gif isn't animated. It's like the gif got converted to a jpeg or something when the phone was syncing. Anybody know how to upload a gif photo to an iphone?

Added (1). And check that out I solved my own problem. For anybody else who searches this: email the gif to yourself then save the image from there.

Is it worth buying the iPhone 4s now if the 5s is going to come out?

I want to get an iPhone but I'm scared my iPhone will yesterdays news. I don't want to spend a lot of money so I know I'm not going to get the newest thing. That is why I want to get an iPhone that's one model behind. At AT&T the iPhone 4s is only $100 but I heard the 5s will come out in September. With my experience with apple the older generations seem to stop working. Like I have an iPod touch that's only 3yrs old and it's not compatible with most apps.
