Microsoft Singapore officially launches Windows Phone 7.5 yesterday. Windows Phone 7.5 has more than 500 new features and enhancements.

Both HTC Radar (RRP: S$569) and Samsung Omnia W (RRP: S$498) will be the first Windows Phone 7.5 to be released in Singapore. The HTC Radar will be available next month (October 2011) while the Samsung Omnia W will be available sometime in Q4 2011.

The Mango release is available for free to all Windows Phone 7 customers. Microsoft will begin delivery of the update to existing Windows Phone 7 users from today and gradually ramp up delivery so that the update will be broadly available to most existing customers by the end of October 2011.

Based on the official site, Where’s my phone update?, both SingTel and StarHub are in the status of “Delivering update” which means:

Microsoft has started to send out the update. Important: To help ensure quality, software updates are typically sent out gradually and/or in batches, so it might take several weeks before you receive notice that an update is available for your phone.
