iPhone 4 running very slow on ios7
I've removed nearly all my apps,
I've removed all my songs and movies etc
I've removed all my photos
I've done a system restore reset
The above did speed it up a little but It is still running extremely slow since updating to ios7 and gets slower every update since
I can't roll back my iOS back and therefore my phone has been ruined by this update
I can't call apple as I don't have the extra cover to get support
Does this mean I'm stuck with a slow phone
iPhone 4, iOS 7.0.4
