How to speed up ios 7 on my iPhone 4?

I current own an iPhone 4, and everything I do is slow with ios 7. Settings and camera app take longer than necessary to load, animations are slightly stuttery when switching to the passcode pane. Notification center and control center take 1-2 seconds more to show up and my phone froze up once when choosing a ringtone. Please help! Greatly appreciated. :)

Also, the photos app takes longer than necessary to load videos and photos!

The iphone Is still deleting old system files, it will eventually speed up but a fast way to speed it up is to completely restore your iphone. Associate all contacts/calendars with an email account that way they are easily recovered after restore. (Do not restore from backup)

Well if it's the same as a computer then when you put a new OS on a pc it rubs slow because it's indexing still.

There is also a mini-Varsity on the campus of Reinhardt University in Waleska, Georgia. Frank Gordy met his wife, Evelyn, at Reinhardt in 1924 and went on to Georgia Tech to finish his education. Their custom-designed home was later moved from Atlanta to the Reinhardt University campus. The Gordy family gave part of their land to Cobb County for what is now the Mountain View campus of Chattahoochee Technical College and the Mountain View Aquatics Center, the rest was sold in the 1990s for upscale tract housing and strip malls. Gordy Parkway, a loop named for Frank Gordy, serves all of these.
