It was previously impossible to easily synchronise your iPhone's notes between devices, but yesterday's iOS4 firmware update adds a feature capable of saving notes directly — and conveniently — to your Gmail account.
Using Google Sync we've been able to sync Google Calendars, Mail and Contacts to iPhones for a while now, but the ability to transfer Notes in either direction remained relatively untouched. This iOS4 feature requires an IMAP email account, such as Gmail or Yahoo, to work. All newly updated iDevices running iOS4 will display an option to activate the ability to save Notes online through the Mail account settings.
In Gmail, Apple creates a label called "Notes" in the linked account. Any notes that are transferred will use this label and are only editable from an iPhone or iPod Touch, making it, unfortunately, a one-way sync. Specific notes can also be synced to different accounts. (In the the top-left corner of the Notes app, an Accounts button dictactes the syncing behaviour of each note.) This feature is only available through iPhones and iPod touches running the new iOS4 software.
The feature skims the surface of several recent software changes Apple has made, so check out our guide to the new iOS4 shortcuts, features and settings for a full overview.
