Ultrasn0w iPhone 4 unlock available now

It wasn’t long ago that the United States government made it legal to unlock/jailbreak the iPhone (as long as it is for the purpose of switching carriers). That news may very well have had the developers behind the most popular jailbreak method – ultrasn0w, breathing a sigh of relief.

They are now free to legally distribute their application without any worry that they would be targeted for a lawsuit. The dev team also has announced great news for iPhone 4 owners today. They have released the updated version of their unlocking/jailbreaking tool, now supporting iPhone 4 users.

According to Engadget via The Dev Team Blog, “It's the moment that many of you have been waiting for: the Dev-Team's ultrasn0w carrier unlock for iPhone 4 is out. You'll find version 1.0-1 of ultrasn0w in Cydia on jailbroken devices.” Jailbreaking is the act of freeing the iPhone from the restrictions that apple’s default settings provide. It allows users to install custom software from a wide variety of different places without the need to use the iTunes App Store.

Jailbreaking has been extremely popular among the technology enthusiast community. Unlocking allows users to use the phone on a carrier other than AT&T, as well as install custom themes, home screens, and applications not available in the app store.

Jailbreaks and unlocks are software based and restoring your iphone on itunes put your iphone into factory setting thus un voiding your warranty.

Unlocking allows different carriers Ie, vodafone, Orange, Rogers, and jailbreaking allows custom themes, custom apps etc.

Sorry I'm new to iOS, I've jailbroken using this where can I find custom themes?

I thought getting an iPhone 4 offline in UK and other various European countries are not locked to a single Network?

Offline???

If iPhone's are bought through a carrier here in uk, they are locked to that provider. You can request an unlock from provider and pay, or use things like ultrasn0w and void your warranty.

Yes, but Android comes with its own set of restrictions (including things iPhone users take for granted, like taking a screenshot) that requires rooting the device, so things even out I think.

But what useful, everyday things can you not do with an unrooted Android phone? Screenshots are irrelevant for most people.
