I want to know if I can make my old linksys router into a signal booster for my new Wi-Fi router if so how would I do it and what settings would I have to change to make it work with my other router and can both routers be close to each other because I only have one computer set up in my house but lots of wireless electronics such as my iPhone and laptop.

IMessage won't activate on new iPhone 5S?

I recently purchased a new iPhone 5S from Phones4U, it is on EE.
It won't allow me to activate iMessage or FaceTime. It comes up saying there was an error and to try again. No matter how many times I retry it still won't work, the same message keeps re-appearing.
I have 10GB of data allowance, I've tried it with both my Wi-Fi and cellular data switched on and it didn't work, then I tried again with just cellular data on, on its own and it still doesn't work.

I've checked all restrictions and FaceTime isn't restricted.

I followed the steps on the Apple website about troubleshooting and still no hope.

Has anyone else had this issue? How do I get it to work?

Posting audio from a concert. Is it illegal?

Last summer I got the chance to see my favorite band live. During the concert, the lead singer did an acoustic version of one of their songs and it was beautiful. I recorded a video of it on my iPhone and I was thinking about stripping the audio from it and posting it as an audio post on Tumblr. I run a fan blog for said band, so I know my followers would really like to hear it. Is this illegal, though? It's obviously not a high-quality recording, and it would only be one song. Could I get in trouble for it? Thanks!

Added (1). It's obvious, but I thought I would just add: I obviously wouldn't be selling it, making a profit off of it or let other people download it. I just thought it would be a cool thing for people to hear.

My iphone 5 is brand new and takes forever to charge. Why?

I just received the phone in the mail two days ago and for the first charge I took it out of the box, plugged it in and it was completely dead. Took over an hour to start up, and after 12 hours of charging wasn't even at a full charge. Should I try and get it repaired?
