Please believe the negative reviews – FastSync for GmailContactsLite Review

Much to my horror, I realized that iPhone 5 does not support gmail contacts- unlike the iPhone 4. I thought this app would solve the problem- it does not. It syncs the contacts - but does not transfer addresses. You will have to do that all manually. You might as well save the money and find another fix. Be forewarned- definitely NOT worth the money!
