Sorry if that word (jailbreak) is not allowed in here. I have an iphone 5s with IOS 8. I really don't like it and it's made my phone slow. I want to go back to ios 7 and the only way I can see this happening is if I jailbreak my phone and install a jailbroken ios 7 firmware. Can I do this? And if I did - will it still connect to app store to buy apps? Or is there any other legit way of installing ios 7 on my phone?
