Factory Unlock iPhone 5, 4S iOS 6.1.3, Including iPhone 4, 3GS After 6.1.3 Jailbreak – Although the majority of questions we receive at Evasion Jailbreak are related to jailbreaking, iOS 6.1.3, downgrading and our expert jailbreak tutorials, a number of our users often inquire about unlocking their iPhone 5, iPhone 4S, 4 and 3GS models. In this article, we’ll highlight the best type of unlock and how any iPhone model on any baseband, running any firmware, including iOS 6.1.3 can be easily unlocked. Before we begin though, it’s important to realize that unlocking is fundamentally different from jailbreaking in that it allows an iPhone to be used on carriers other than the one it was initially intended for and essentially “locked” to. Although jailbreaks and unlocks can coexist, the two are entirely separate. For the latest on jailbreaking, we recommend reading our recent article on the topic.
