So, i had 7.0.4 jailbroken on my last iphone. I got it replaced because the home button was going out and it wasnt reading my sim card. The replcement phone came with 7.1. It was laggy even when using it vanilla. So i restored to 7.1.2. Laggy even when it was non jailbroken as well. Restored to 7.1.1. Terrible both jailbroken and vanilla. To unlock the phone, if i press the sleep button to wake it, it turns on then off after i press the button like 5 times. Then if i press the home button, it activates siri instead of waking my phone. The only OS thats being signed right now that doesnt lag horribly is 8.0... This is ridiculous.
