I have an iphone 4s which isn't jailbroken. OS is iOS 6.0.1. I don't want to install iOS8 (due to slow and battery issues) and can't find any way to install iOS7.1.2 directly from iTunes.
Can I use jailbrake somehow to be able to install iOS7.1.2 on my iphone? if so, how to should I do it?
Thank you for your help!
