How to permanently unlock iPhone 4?

Hi, i would like to unlock my iPhone permanently. Before Christmas I bought my son a iPhone 4 for Christmas. It is att locked and my son jail broke it. Now my family wants to travel to Europe starting August. Currently my son is on a att go-phone plan and we do not want to pay large sums for going abroad. Is there a way for permanently unlock? Att can't unlock it because the phone does not have a account with a 2 year contract. Is there any other way?

Also my son ever since October, has been hyped about the Galaxy Nexus, however in December the phone cost 700, now on eBay it costs around 300-400 (same price i paid for iPhone 4 in Dec). Should i sell the iPhone and get the Nexus. He loves android (especially with new "Jelly Bean" OS coming out) and the Nexus works on tmo "4g" network. However i think that buying a new phone will be too much of a hassle (and time consuming) and the probably of switching phones is less than 20%.

Transfer all songs from an iPhone to iTunes?

I had somehow managed to delete all my songs from my computer and thus, they were deleted from iTunes as well. However, I still have all of the songs on my iPhone and I was wondering if there was a free yet efficient way to transfer all of my songs from my phone to iTunes again.

I have the 4s, if that will help any.

Why isn't my iPhone charger working?

I have an iPhone and it was working fine but yesterday when I plugged it into my phone it would not charge. So I tried my brother's iPhone charger and it worked. I looked it up online and I think there's a problem with my USB cable and not the wall charger itself. What do I do?

Best iPod/iPhone dock for under £50?

I'm going to buy a dock in the next few days but need some reviews on ones you have or have used before.

My priorities are: I'm only going to use it in one room so portability isn't needed, a remote would be handy, good quality sound, and maybe an aux or 3.5mm jack and a subwoofer would be great!

£50 is really ideal, i don't mind if it's used so you could give me a few options orone slightly more expensive and nothing like a bose as i can't afford one unfortunately!

I have looked at the Sony SRS-GU10iP and IWANTIT IPH10011, they look good options for me.
