The Dev team (as we speak) are working on a SOFTWARE unlock, I have heard they are very close and should have one very soon. If you would like to follow their progress here's the link to their blog: http://blog.iphone-dev.org/ Method of unlocking iPhone 3G Now, if you would like your iPhone 3G to be unlocked there are a couple of ways doing it (however, these methods are very similar). You can buy the Turbo SIM or Universal SIM (I'm sure there a few others out there as well.) What these 'sims' do is temporarily unlock your iPhone 3G i.e. if you were to take it out then your phone will be locked again. - How they work: They are these little thin pieces of plastic that sit BETWEEN your SIM that you choose to use and your SIM tray. You push your SIM tray in and it will take a few minutes to recognize your SIM. Then everything works fine. - My personal experience: I, myself, use one of these 'Turbo SIMs' and so far it has worked perfectly. I also have a friend that has had it for about 6 weeks now and he has had no problems whatsoever. The only negative thing I can say about it is they MAY be a little tricky to get in at first but you get used to it. Also, when you plug it into iTunes it comes up with the 'insert valid SIM card' screen. All I did was pull out my SIM tray, unplugged and plugged in again and it worked fine. This is my problem, I do not know if anyone else has had this problem. - Where to buy: There are many sites which sell these, however personally I think they are too expensive and try to rip you off. I bought mine off eBay for $10 (very cheap). If you want to buy one I recommend you buying one off eBay (just make sure it's a trusted seller and they have good feedback) Well, there you are. This is basically where we are with the whole iPhone situation. Hope this helped. Thanks.
