[Update 11:20: Microsoft has now updated its “Where’s my phone update” status page showing that carriers are now starting to deliver the update.]
Microsoft has updated its “Where’s my phone update” status page, showing that most carriers in the U.S. are scheduling the latest Windows Phone update — codenamed Mango — for delivery to existing Windows Phone users. That’s a phase that typically lasts 10 business days or less.
Among major carriers in the U.S., AT&T, T-Mobile, and Verizon are all in the scheduling phase. Sprint is still in the testing stage, meaning the software update is undergoing mobile operator network and quality tests, according to the status page.
Internationally, most carriers indicate they’re scheduling the update for delivery as well, with only Telefonica in Spain in the testing phase.
Even after the scheduling phase ends, however, the software updates are typically sent out in batches, and “it might take several weeks before you receive notice that an update is available for your phone,” according to Microsoft.
Mango, officially called Windows Phone 7.5, is the latest update to Microsoft’s smartphone operating system. The company said last week that the update would be rolling out this week or next.
