It looks like Google has rolled out a rather nice update in terms of Google Sync for iOS devices. And the nice part, these latest improvements work with the native email and calendar apps which means you will not have anything to worry about downloading and/or updating. Furthermore, these will work with both Gmail and Google Apps accounts. In terms of the improvements, they include the ability to;
- Search all your emails in Gmail, not just the emails stored locally by the iOS mail app.
- Accept, decline or edit calendar events from the iOS calendar app.
- Send email from the address you want. We recognize that some of you manage multiple email addresses from a single Gmail account.Gmail’s “Send Mail as” feature lets you send messages with another email address listed as the sender instead of your Gmail address, e.g. firstname.lastname@example.org instead of email@example.com. Now the iOS mail app will respect these settings.
