Previously on my i4 I had gmail setup as exchange and used the stock MAIL app and it did everything I wanted. Now that I upgraded I lost the exchange functionality as apparently google removed it for us iPhone users forcing us to use the GMAIL app. Is anyone finding the APP slow? Sometimes just terrible and not loading always promptly? What are my options? Want to keep PUSH for my gmail account on my iPhone 5S.. Is GMAIL app the only one?
