The latest Springtomize has messed up my safari. Whenever I go back a page, I can't scroll. If I wait several seconds though it'll unfreeze. This started "working" after a reinstall, prior to that, the freeze was permanent until I hit the home button and then reopened the app. I didn't have to kill the app though for what it's worth.
I'll try to reset everything to default and then reapply my settings and see if that stops the temporary freezing.
