Search for "iPhone GBA emulator without jailbreaking". Set your calendar back to July 15th, 2013. Install, start up the emulator, then set your calendar back to normal. Enjoy!
I had to wipe my iPhone to get it replaced and they didn't come back onto the phone. I had them on iTunes but I as well had to wipe it to get it fixed... Just my luck.
Yep. Just remember that you have to do the same thing (set back the calendar) every time you do a hard reset on your phone.
