I was attempting to enter appointments as usual into my calendar. When I finished, a white bar appeared on my screen that I couldn't remove. I restarted my phone and all of my calendar appointments disappeared. Including every previous appointment ever made. Not only that but my battery life is half what it used to be since the upgrade to iO7. Upgrading to iO7(x) was a huge mistake. I consider this a major downgrade and I refuse to be forced into buying the new i5(anything) because of Apple's underhanded attempt to push sales through unethical trickery! Shame on you Apple Corp.
