Im due a phone but not sure which phone to get.
This is NOT a My Phone Better than yours thread.

Current phone Galaxy s2. Love it, been a really good phone, i use it to tether sometimes because my internet connection can sometimes be dodgy where i live. also like how i can use it as a portable storage device, and like how "Free and open" Android OS is.

But i Have a Macbook Pro and it is the best Cpu i have ever owned. So im thinking Maybe Iphone 6.......
Only Downside is i Have over 2000 Tunes on my iTunes, Will these need to go on my Iphone if i get one? Can i tether? im sure you cant use as portable hard drive without Jailbreaking....

The phones i have in mind are... Htc One Mini, Galaxy S4 Mini, Or Iphone 6.
Thanks.
