iPhone 4 photos wont rotate
Hi,
I had this problem and I was pulling my hair out.. However I finally figured out the answer!
The problem seems to occur when too many programs (or problematic specific one(s)) are running. The cure was to double tap the Home button to bring up the multi-tasking bit.
Then hold your finger on an application to make them wobble and bring up the delete symbol.
Next delete all the programs that are currently shown there - ie are currently multi-tasking.
Your rotation should now be back working.
I guess you could work out which program(s) cause the problem, but I haven't been that sytematic yet!!
(incidentally - I had to do this after closing Co-Pilot too so that it turned off the GPS and stop my battery draining!)
Hope this helps
