Is your Wi-Fi connection fast with your iPhone 5?

I've got an iPhone 5 and its Wi-Fi connection should be very fast, as Apple said. Nevertheless, my iPhone 5 in Wi-Fi is slower than my pc (Windows) that is 6-7 years old. Especially in YouTube, it's often impossible to me watching HD videos, because it loads them too slowly. Is it normal? If I took my iPhone to an Apple Store, they wouldn't find any problem, because it's an occasional problem; some days it's "fast" (normal), some days it's slow. That's very annoying! I've also installed today iOS 6.1 but nothing has changed.

Reserve battery on iOS devices?

A few years ago, one of my friends told me that you can access the extra 20 percent of battery from your iPhone, and he did it though MobileTerminal, does anyone know what to type (after getting into super user) and what to install in Cydia?

Can you use samsung galaxy s3 as a mp3 like iphone? Also, Ipod Touch 5 or IPad mini?

Bought a Samsung Galaxy S3 recently (still on its way from delivery), and going to sell my IPhone 4 and buying either an IPod Touch 5 or an IPad mini.

So first of all, I'm someone who listens to music whenever and wherever, so for me, the Itouch seems like a suitable device for me, seeing as it'd fit nicely in my pocket and easy to carry.
But, I also use my laptop a lot to study, and when I don't carry it around, i use my iphone. But its a hassle because the screen isn't that big.
So my question is, is the galaxy s3 similar in mp3 style to the iphone? Because if so, I'd be leaning more towards the ipad mini, but if not, interested in Itouch.
Also, another question is, what can ipad mini do to help with education?
I have a brother who uses it for uni, but no idea how.
Are you able to download like powerpoints or word document and things like that?

How to put a bigger picture on instagram like before?

On the oldest version of instagram you could put bigger photos on (vertically length wise) by rotating the photo so it's sideways in your album, then when you go to put it on instagram just rotate it while your in editing. So you end up with the whole photo on there, the edges are just black. You can't do that on the new version though

How can I find a new way to put pictures like that on without cropping them?
Or just get the older version of instagram on my iphone again?
How help?

How to recover deleted note on iphone that wasn't synced or backed up?

One of my most current notes on my iphone seems to have gotten deleted, although i'm almost certain i did not do it myself.
Anyway I haven't synced it to my mac in weeks and I don't think it has been backed up through icloud…
Is there anyway to access some sort of recovery mode where deleted notes might be stored?

How to use a iPhone 4 without a sim card?

I got my friends old iPhone 4 without a sim card. I just want to use it for music and apps through Wi-Fi, like an ipod touch. It's on 6.0.1 and on the screen used when regestering and authenticating your iphone. I tried to jailbreak it and it said to use redsnow but that wasn't working. Is there an easy way to bypass the authentication screen permanently, like an easy jailbreak or secret trick? (I know the call 911 and quickly hang up thing, but once your lock your phone it resets.)
