According to the Nokia Software Update Tracker, the Lumia Cyan update should now be available for my phone model, region, and carrier. It has been available, according to that site, at least since yesterday. However, despite multiple checks for updates over the past few days, my phone is still reporting no update is available.
I thought this might be a problem caused by the Developer Preview I'd installed to get an early-release update to Windows Phone 8.1 on my phone. However, my parents have the same phone model and carrier (and do not have Developer Preview) and their phones also say no update is available.
Is there something wrong with our phones, or is such a delay to be expected even when availability is announced (again, specifically for our phone model, carrier, and region) on Nokia's site? Is there another way to get a more accurate estimate of when we should expect the update to be available for our phones?
