I actually do this to my phone on purpose because every time I reboot the phone I lose some icon pictures. Going into another language gets them back. But the first time I did this I picked Japanese, a move stake as I don't know any of that language. Anyway , I learned to go into General, go down 6 sections and the 3rd line (bottom) in that 6th section is what you want. When you press that you usually see the language list and Rnglish should be #2 on that list.
