Bidding AT&T Adieu: Hackers Release iPhone 4 Unlock

August 4, 2010 By Nick Mokey

A new version of ultrasn0w now works for the iPhone 4, allowing owners to take their iPhones off AT&T.

Just days after opening the iPhone to non-Apple software with the simplest jailbreak procedure yet, hackers have further liberated Apple’s iPhone 4 with a carrier unlock, which frees owners from AT&T by allowing them to use their iPhones on any GSM network.

After jailbreaking an iPhone 4 with the simple, Web-based unlock released earlier this week, owners can download an updated version of ultrasn0w that now works on the iPhone 4, iPhone 3G and iPhone 3GS. It’s available for free today through Cydia, an app which acts as a distributor of software (similar to Apple’s own App Store) on jailbroken devices.

As with previous iPhones, a jailbroken and unlocked iPhone 4 will be able to make voice calls and access the EDGE data network on T-Mobile, but does not support the frequencies required for 3G speeds. (AT&T uses 1900MHz for 3G, while T-Mobile uses 1700MHz and 2100MHz, frequencies the iPhone 4 does not support.)

Nick at 4:49am 6th January 2011 I got a "iSpot" from Clear. It's 4G speed and you can jailbreak your ispot with a easy web browser webpage script which loads and does it's thang with llthe iPot modem and unlocks it so any device can use it's connection not only Apple products. Now that's freedom. And it's portable. So I have to say it was easy and quick to jailbreak my ispot and way worth the $25/mon bill for unlimited 4g portable Internet. Don't bother with Clear's customer service though, it's a joke! They are the worst customer service experience I've ever had in my entire life. I'm not kidding. Their online forums were much kore helpfull than trying to communicate and much less try to solve my problem by talking to one of clear's customer service reps. Omg.
