We’ve been talking about Microsoft’s plans for the next big Windows Phone 8 update, GDR2, for months now. Some of the picture of how the update would arrive has been clear: for instance, we know that Nokia models will start getting their “Amber” updates next month, and that’s going to be tied-in to the release of GDR2. But with how inconsistent Windows Phone update distribution has become, that’s hardly confirmation that other OEMs would be working on the same schedule. While still incomplete, we can now put together a slightly more encompassing picture of update availability, thanks to Telstra in Australia.
The carrier just updated its chart of current and upcoming smartphone software release. This now includes GDR2 for not only a couple Nokia models, but the HTC 8X and 8S, as well. According to Telstra, it anticipates granting approval for the 920′s update on July 8, and approval for the 520 and those HTC models on July 15.
What it doesn’t know yet is how long after those approval dates will its users be able to start installing the software. Sometimes, that can be as quick as a day, while other times it takes two weeks or more. This schedule will also likely differ with other carriers, but at least this gives us a rough window of when to start looking.
