Why is IOS7 for iPhone 4 so Slow?
? It's not slow if it is slow it might be it internet connection. Or u have to many apps like say u have a app with a lot of MB witch will cause the app to be slow sometimes it makes your internet slow or u might have 3G
It might just be your phone because I have it on my iPhone 4 and it works great.
Some earlier phone versions might not work with an update made for later phone formats. Some of this might be internet connection, cellular service or over using your phone.
since ios 7 is new its probily a bug
