If you are still clinging to one of those Windows Phone smartphones running version 7.8, you should start planning to replace it with a Windows Phone 8 smartphone, as Microsoft has announced that mainstream support for Windows Phone 7.8 will end on the 9th of September 2014.
Well, its not actually that bad. Your WP 7.8 device will still work, but it will not receive any more new features or performance updates. I still have my Nokia Lumia 610 lying in a drawer. It runs Windows Phone 7.8. It is over a year and a half old now, and while no longer in good shape, it still works.
Update: I asked a few questions from a Microsoft/Nokia exec, and was told that Windows Phone 7.8 apps will continue to be available in the store.
Do you have a Windows Phone 7.8 smartphone? Do you have plans to replace it soon? What devices are you looking at as possible replacements?
