I found a fix!! Refer to this article regarding using Microsoft Exchange for Google accounts: http://www.zdnet.com/with-new-gmail-and-google-maps-ios-apps-the-iphone-5-is-cle arly-the-best-smartphone-available-7000008756/
In a nutshell, the Google/Microsoft Exchange combo will no longer work on apple devices. You will need to delete your Exchange account altogether. I know, scary! After you delete it, add your Gmail account like you would add any other regular email account on your device [Settings > Mail, Contacts, Calendars > Gmail > add your info]. That takes care of your email and calendar.
Now to get your google contacts back! Refer to these instructions: http://support.apple.com/kb/HT4872?viewlocale=en_US
I promise, these steps worked for me (even though I was wincing while I deleted my Exchange account). Now I have my Gmail, Google contacts, and Google calendars (even the shared calendars!) on both my iPhone and iPad :D
