My Internet is slow when it shouldn't be

When I do a speed test on speedtest.net or something like that. It says that my download speed is 9.3Mb/s, however whenever i download anything, for example, The walking dead on Utorrent it is only downloading a 1.0KB/s max. Its the same with downloads on my Iphone!
Any idea what's wrong or any solutions?

What does apples one year warranty cover?

?

I recently got a free iPhone 4 from sprint with a new 2 year contract. It's almost 2 months old, and I went to take the charger out and my whole charger port came with it. Other than that there's no damage to the phone does apples 1 year warranty cover this? If not or so is there a cost? Roughly. My sprint store apple should cover it since there isn't water damage, but I wanna make sure before I go all the way to the store to just find out they don't.Ps I didn't get insurance with the phone but they said it was okay because apples warranty.

Music on my iPhone is not showing up in my iTunes?

I have a playlist on my iPhone that contains songs that I have bought from iTunes and songs I have from elsewhere, and neither the playlist nor the songs that I have that are not purchased from iTunes appear in my library. The simplest thing I can think of is copying the playlist and pasting it into my library, but this does not work.

Does anyone know how I can fix this?

What information should I include in my add to sell my iphone 4 on eBay?

I'm selling a black iPhone 4 16g (Verizon) on eBay that I'm not using anymore. I took pictures that focus on the imperfections of the phone because it is used and not perfect but it's still in good condition, I definitely want to make sure I leave no stone unturned and make sure I give the buyer all the information they would need to know before buying the phone to avoid any conflict, so please comment with suggestions!

My computers USB ports won't work

I have a compaq presario CQ62 running on windows 7. Recently my ports have stopped working. I have tried pretty much everything! It's really frustrating because I recently updated to an iPhone 5 and I couldn't back up my iPhone 4. Went to apple and they managed to back it up but still couldn't recognize my 5! I've managed to transfer everything from iCloud (which was a very painful process)

My laptop will sometimes recognize my USB but will never recognize my phone. I have tried uninstalling and reinstalling iTunes with no luck.

I'm getting pretty desperate now.
Any advice is welcome!
