Can i turn my apps off on my iphone (4). If so, how?

What do you mean off?

If you mean by not sync them or delete them all then go to iTunes, the iPhone tab where your iPhone is, the Apps tab, then unclick "sync apps"

If you mean to stop automatically downloading them if you download them from another device, on the iPhone go to Settings, iTunes & App Store, and turn off automatic downloads

Off?

If you meant make sure they aren't running, just double tap the Home button, press & hold any app icon until they wiggle & press the minus sign to shut them off.
