Alright so I need some assistance.
I feel like Apple is messing with my phone just to get me to buy a new one and I'm just not ready for that yet. Pretty much, I have a 32 Gig 4S, I updated it to iOS8 back when it came out, it used it for a day or so before I reverted back to the last version of iOS7 because iOS8 was making my phone run too slow.
Well, ever since then my phone has been running extremely glitchy and laggy. It went back to doing that thing where it doesn't keep any of my background apps running, so every time I go back to something, it always refreshes and doesn't stay loaded with the last thing I was doing on there before I hopped to another app (safari, twitter, tumblr, pretty much everything), they fixed that in one of the updates but for whatever reason it's reverted back to doing that.
Along with my phone freezing and restarting every time I open the camera app, along with general random freezing and crashing way more than usual.
I tried to re-install iOS7.1.2 but Apple is no longer validating that through iTunes. Is there anyway I can work around this to re-install and get my phone back on track? When I reverted back to iOS7 from 8, I downloaded the ISPW file from Redmond Pie if that means anything. I've used them in the past for jail breaking and stuff so I figured their files would be fairly reliable, unless something has changed?
Any help would be supremely appreciated.
