Bug in update: endless loop

I have an iPhone 3. Old version worked fine. But suddenly the ONLY option is to update. But I get a message saying update requires OS 7 but would I like to download an older version. I say yes and wait for it to load. When I try to open it I get the mandatory update notice and we go around the merry go round again! Ive been trying every couple of days figuring they would catch the glitch. Nope. Im locked out. With no way to report the bug. Come on Zynga. Get your act together. I PAID for this game.
