I downloaded iOS 7 on my iPhone 4 (CDMA) an now it's slower and glitchy?

How can I fix this? I downloaded it after backing up and and restoring it then I restored the back up with iOS 7 but my phone is really really slow, like everything is delayed especially when I type

Oh no! You mean your unofficial software is acting up? C'mon man, wasn't this expected a little bit?

and I'm no apple guy, but you arent the first to ask about this. And the others were saying you can't go back to iOS6. You have to wait until fall to get the official build… Yikes.

maybe a factory reset will fix it up, and don't restore anything. That migh fix it.

If you are not a dev your iphone will be disabled on or before july 22nd.

  • Why is my iPhone so glitchy? My iPhone has been glitchy lately. For instance, I would hear my text Tone go off an I'd check the phone and there would be no text notification displaying on the front screen. Or sometimes when I would turn my phone on I'd receive old-late messages from hours ago… How can I fix this?
