After the massive T-Mobile Sidekick outage last week Roz Ho from Microsoft has put out a full apology to T-Mobile users. What is of note here is that Roz is the Roz Ho Corporate VP of “Premium Mobile Experiences” at Microsoft and is working on Pink, the chassis framework for Windows Mobile 7 Windows Phones. Edward over at MSmobiles suspects this means that the big “microsoft phone” that is always rumored is in fact just the next Sidekick.

I’ve always found Microsoft’s purchase of Danger ages ago curious, considering the lack of any significant movement on their mobile platform in years now. I’ve just been giving them credit for seeing the big picture: Danger’s Sidekick had some really neat features when it first came out with server-based management of every single Sidekick out there – all your data was stored on the Danger servers and could be accessed through the web, long before Microsoft MyPhone was even conceived of. This ultimately led to the big blackout last week.

This system is similar to the BES (BlackBerry server) style solution from RIM, which is one of their main competitive advantages over both all of their competition. Could Microsoft be looking to deploy a BIS/BES-type network in the future? Offering enterprise the same ultra-secure and manageable environment as the BlackBerry, built on Danger’s original device management systems and integrated with Microsoft’s server solutions (i.e. OS and Exchange)?

This would give Microsoft some of the benefits of Apple and RIM’s vertical market strategy. While RIM tries to tackle the consumer market and Apple tries to prove itself to the Enterprise market, maybe Microsoft – with its patience and experience – has been quietly planning to trump them all?

Time will tell…
