Before the iPhone 4, I had the iPhone 3G. I used Google Sync for push gmail (and only push gmail) when it first got announced, that worked great for a month or two. Then suddenly emails wouldn't come in until hours later, even when I would refresh it...it just wouldn't show up in my inbox. So went back to IMAP, tried Google Sync again a few months later and same thing. So decided to stay with IMAP, and haven't tried Google Sync again since. So who here, specifically on the iPhone 4, is using push gmail with great success? Other iPhone users?? Also, I have recently started using iCal to keep up with work / events, does Google Sync allow you to wirelessly sync your calendars from your iPhone with "iCal" on your mac? What about contacts on your iPhone with "address book" on your mac? Do I need to install any software on my Mac to make this happen? Paid / Unpaid...I don't mind Thanks!
