If you’ve been paying attention to T-Mobile’s problems with Sidekick backups this week, it’s probably made you think at least a little bit about how you back up your own mobile data.  Of course, given the Sidekick’s problems, it’s also possible that you may be a little tentative about the cloud at the moment.

If you’re willing to give the cloud a chance, then Best Buy’s new venture may be of interest.  In conjunction with Dashwire, Best Buy is introducing its own cloud backup service, called mIQ.  mIQ works with Windows Mobile, BlackBerry, and Symbian S60 operating systems.  The service goes active today (October 12), and you can sign up for a free account with 1 GB of storage.  If you purchase your phone at Best Buy, the blue shirts will install it on your phone in-store via Best Buy Mobile’s Walk Out Working program.

According to the mIQ website, “mIQ takes the content on your phone and automatically pushes it to a private account on the web. From that point on, what you do on the phone will instantly update on the web and what you do on the web will instantly update on your phone – without you having to ever think about it.” In addition to backing up contacts and calendar data, mIQ also includes enhanced text messaging, photo and video storage and organization, and connectivity to Facebook, FriendFeed, Flickr, and Twitter.
