Microsoft has launched the MyPhone service to the public. An earlier beta version was released in February, but not it was available to any Windows Mobile user who wants to try out the over the air back up service.

The service is compatible with any Windows Mobile 6.0 (or greater) phone and allows users to have 200MB of online storage space to back up any files they wish to access at anytime through your phone or computer. At this point the service is quite basic and the storage space is limited, but if you’re just looking to save your contacts and text messages 200MB should be more than enough to keep you covered.

Another useful feature is a restore function which will allow you to transfer data from your previous phone (whether you have it or not) to your new Windows mobile phone. So did you “lose” your HTC Touch Diamond and now just have to upgrade to the Diamond2? Well don’t worry your little fingers. You won’t have to be typing all of your contacts in again if you’ve already backed up your info to MyPhone.

The beta version is currently in development and other features which are expected to be added are GPS tracking to find lost or stolen phones and also remote data wipe which will let you delete all of your personal information off of a phone that has been stolen.

Right now we think the service is too simple to go nuts about, but it will be interesting to see how it develops in the lead up to Windows Mobile 6.5 and the hotly anticipated Windows Mobile 7.
