Google announced yesterday that Google Sync is now available for the iPhone, adding it to a list including the Blackberry, Windows Mobile devices, some Sony Ericcson and some Nokia phones. The iPhone, Blackberry and Windows Mobile devices will synchronise calendars as well as contacts in the address book. Is this enough to replace Mobile Me if you have a Mac as well as an iPhone?

Mobile Me is a paid-for service (£69, $99 per annum) that enables the near real-time synchronisation of calendars, contact information and a number of @me.com email addresses. It’s built into OSX and the iPhone and (after initial teething problems) has proven to be a reliable way to keep the information on your Mac in synch with your phone. But even with its other perks – 20Gb of internet storage, email addresses – it’s expensive. Can Google Sync now be used instead?

The answer is yes, but there are compromises here. Firstly, you lose those perks. Secondly, if you’re using Activesync on your iPhone already it simply can’t be done – Google Sync requires Activesync and there can only be one Activesync configuration. Thirdly, it’s nothing like seamless. You need to set up Address Book, create new calendars, move data around and back up regularly – this is a beta after all.

However, if you wish to replace Mobile Me, or if you use one of the other Smartphones that work with Google Sync, this is an interesting opportunity. At the very least, I hope it will cause Apple to revisit the pricing of Mobile Me. I’ll pay for simplicity of configuration, but I don’t think I’ll be the only one who will think “is this worth it any more?” when my Mobile Me subscription rolls around again.
