Last week, and ahead of the official launch of Windows Phone 8.1
, we reported that Microsoft had reached the RTM milestone
with its OS update, and that its code had been finalized ready for distribution to Microsoft’s partners. But it turns out that things are a little
more complicated than that.
As we reported, Microsoft did indeed sign off on the Windows Phone 8.1 build – what the company refers to as “the final feature build” – on March 26. On the same date, that build – 9651.12349 – was made available to Windows Phone partners via Microsoft Connect.
But that wasn’t actually the ‘final’ build; indeed, WPCentral
pointed out that a few bugs still needed to be exterminated in the OS, suggesting that this process was likely to take a couple of weeks.
