Google’s been cleaning house lately and as of January 30th, 2013 most Gmail users will no longer be able to sign up for Google Sync.
When first setting up a Gmail address on an iPhone one would assume the vast majority of people would choose Gmail from the list below.
Turns out if getting your emails as quickly as possible is important to you the better choice is Microsoft Exchange. By setting up Gmail as an Exchange account (using Google Sync) you’re able to configure your emails to be pushed rather than fetched.
The key point here is that Google Sync will continue to work if your phone is configured to use it before January 30th. If you haven’t already done so, now’s your chance. It’s worth noting that you could also use the Gmail app but personally I prefer Apple’s built in app.
