yes, depending on weather you're using a mac or a pc there are several sites on Google. I've posted on here previously about this. I used <a href="http://unlock-an-iphone.com">jailbreak my iphone</a> to help me unlock my phone but if you don't like them there's probably 50 sites on google that will be able to help you. I asked before I forked up the 19 buck if they could help me unlock my baseband and luckily for me they could. I've heard of other basebands not being able to be unlocked but at minimum you can jailbreak your phone which is awesome in my opinion. It lets you do all kinds of really cool things and I get all my software for free now.
yes
all you do is buy a turbosim card off of eBay for 10-15 dollars. you just place the turbosim on your own sim card, put it in your fone, and it will be unlocked to work on any network. I don't know where else you can buy it. look online.
