My iphone 4 freezes and lags a lot with iOS 7?

I recently downloaded iOS 7 for my iPhone 4, when i downloaded it, it started to lag and freeze and the typing was really delayed when i was trying to text. I already tried hard rebooting it(Pressing the home and power buttons until it turned off and back on) and i need to know if i can fix it somehow.

I don't have an answer, but my phone is the same and is having the same problem. I'm going to call customer service.

  • Why does when the iphone 4 connects to the internet, the Wi-Fi lags? Whenever my sisters iphone connects to the internet and i play a online game league of legends for example, i get a very high ping and i start to disconnect and reconnect. Could you help me fix this. Oh btw, my sister won't get off and shut her iphone down.
  • When I pull my notifications down, it lags? Recently i've realized on my iphone 5 that when I get a text message or any notification, that when I pull it down nothing shows up for a couple seconds so then I have to release it and do it again. It lags all the time, mostly for text messages. I'm wondering why it does that because it never use to do that. Its a 32 gb so I have alot of memory to use up still like 13 gbs. I don't know why its lagging so badly.
  • What Happeneds if i jailbreak my iphone and it freezes and/or doesn't work? Like, could it be restored so all of my stuff was still on there? if so how? if my stuff couldnt be restored could i refomat the phone so it still works? if so how?
  • Quicktime lags and VLC plays iphone movie sideways. What can be done in either case? So I had my son take a short vid with his iPhone and transferred it to my HD. When I played it with VLC (or others) it plays sideways. Speed is normal though. Then I played it with QuickTime and the vid played normally (Portrait) but the speed was too slow. QT is lagging. Any help with both issues would be appreciated. Thanks to all. BTW would I need to upgrade codecs?
