How to unlock iPhone 3 without a computer?

My connection is too slow (20kb/sec) to download iTunes onto my computer. I already have an iTunes account, I just don't have a computer to do the initial unlock of the iPhone with. It's stuck on a screen that shows a picture of a usb with an arrow towards the iTunes symbol. How do I unlock it without downloading iTunes?

You can't. Lost cause.

Impossible you need to jailbreak it to get past that screen atleast and to jailbreak you need to.download the.ipsw file and the jailbreak software and that is a bigger.download then itunes itself

You can't without itunes unless it's past iphone 3GS. Tough luck.

It is surely possible you can look at link in my source. It can be unlocked within minutes. Nothing is impossible my friend. And iphone can be used with any carrier. In this era of technology no special training is required.

Get my new iphone 4 mobile a year back which is locked by AT&t network USA, I search for unlocking code for my mobile and i finally found it in http://www.classicunlocking.com/ for cheap cost and also apple network lock guide. This helps me a lot and now my phone is free from network
