...I'm scared! I'm currently using an iphone 3G, but I'd like to buy an iphone 4. Trouble is, I'm relying on a carrier unlock. I've been reading and scouring ebay all day, but I'm still confused. I have jailbroken and unlocked many iphones in the past, but since that was well over a year ago, I'm back to square one (you know how it is ) From what I understand, I will not be unable to unlock an iphone running 5.x unless I happen to get one which is still using an older baseband. What I don't understand is why pretty much everyone who is selling an iphone 4 on ebay has upgraded to the latest version! The ones who were smart enough not to upgrade are charging a huge premium, more than I want to spend. Now, I promise I'm not one of those "PLEEZ UNLOCK MY IPHONE!!! I WILL PAY YOU!!!" morons that post on the Dev-Team blog, nor am I expecting to get a firm answer on when an unlock is going to be released. What I do what to know is whether this is being actively worked on, and if there is any compelling reason why an unlock may never be possible? Reading the Dev Team blog hasn't inspired much confidence. I remember that it used to be a hive of activity, but not so much at the moment. I know that the official policy has always been 'carrier unlock isn't possible yet, and may never be possible', but they've always come through in the end. Is there any reason why this time is different? I guess what I'm asking is, are there people working furiously in the background, or has Apple won this time?
