My Instagram isn't Working

My Instagram account has just started playing up. When someone tags me or something similar, it no longer alerts me on my 'News' tab. Also when I try to comment on certain pictures, my comment is only displayed until I refresh my feed and my comment disappears.

I can still like certain pictures and I can even comment on some but not others, it makes no sense.

I'm on an iPhone 4S and my Instagram is updated to the latest version. I don't know why this is happening! Someone help please.

What are my options when wanting to use an iPhone in the USA for 3 months?

I'm spending the summer in the US, I can't really find a decent plan that I could use my phone over there. I'd mostly need it for calling home in the UK as well as contacting people in the us and maybe some light google mapping - I'd try to keep that to a minimal/ use Wi-Fi spots.
In the UK I pay £30 a month for unlimited texts, 660 minutes and 1gb of internet, any similar deals for roughly the same price?

What is this font? Jailbroken iPhone using BytaFont?

I was searching fonts on google images and this picture came up… I followed the link but I can't find a font name anywhere! What is this font? It SHOULD be a Byta Font font but it looks like this picture was posted last year sometime so I'm not so sure. Thanks!

Should i trade in my iphone again? - 1

SO i got an iphone 5 about two weeks abo and then went on vacation, while on vacation i noticed that i could hear something very loose in the iphone, my brothers iphone 5 had the same sound you just had to shake the phone much harder to hear it. When i returned home i went to the apple store and with a little persuading the apple genius took it back because i was still in my 14 day return policy, i got a new iphone 5 and i have been using it for about a week and now i have noticed that not when you shake it but when you even lightly put it on a surface or tap on it you can hear a rattling like in the last one. Once again on my brother's iphone 5 you have to tap a little harder to hear it and you have to basiclly drop the phone to hear it when putting it on a surface. My question is, do you think i should take this one back and try and get it exchanged or is it something that all iphone 5s have, also do you think apple would even take it, or would they not consider it a problem? Also i was wondering if anyone has an iphone 5 on ios 6.1.3, how long does the battery life last, and have you ever made it through more then a day without having to charge it with regular usage?

Wireless internet connection fail?

Ok so. I have Bright house. We recently upgraded our internet but this problem still consists. Since like December I've been having some internet problems. Every once in a while my computer and iPhone will just stop being connected to the internet. I'm normally playing a game like league of legends or talking on skype or both. I notice it more when I'm on League because i can check the ping. I used to have a steady ping of about 75-90. Now a days i have a steady ping of about 125-150. Nothing about my computer has changed. I've been using this computer for a little over a year. I got it in 2011 for christmas. Not a bad computer 8gb of ram 1.5 terabyte HD just some things i liked. But there are times where my Router will completely stop giving off a wireless signal for about 2 min. Then there are times when I have my ping checker up on League and It would randomly go from like 130 to over 2k ping. Sometimes it's like 400-800 but at it's worst it was about 2k.before we upgraded the internet it once went to 900k ping. I honestly didn't think this was possible. But hey i'm no expert or else this problem would have been resolved already. I normally use google chrome for my internet and i used to run it in the background all the time. Now i can't have too many tabs open in the background or else my ping gets worse faster. But even if the only thing i'm running is League and skype i still get these ping spikes. I would really love to get this resolved any way possible. Even if i have to get a new router/modem.
Ps. And yes it's a combination router/modem. Brighthouse provided it for us.
Tell me if there's any more information that you need to help me fix the problem and i'll do my best to provide them.
