We now have evidence that the HTC HD7 comes with a hidden microSD card slot inside, but Windows Phone 7 is yet to support it. However, there is a way for you to utilize this extra storage — if you dare that is? We have to warn you that it will take a Factory Restore (Hard Reset).
Theunwired were the ones who came across this hidden feature and cannot understand why most manufactures do not go the way of removable and not flash storage, as the former is so much cheaper? In the test, one reader decided to swap the standard SanDisk 8 GB (Class 2) with a Class 6 version microSD card.
We mentioned above that you will have to perform a factory restore (hard reset), this will then allow the card to initialize itself. This was not the end of it though, if you get error messages after that, just try taking the card out and replacing it again.
The guy who did the test did not notice any difference in speed, but it looks as though you could swap the standard 8GB microCard for a larger one — 16GB or 32GB. Being able to upgrade your Windows Phone 7 storage capacity has just made things much more interesting — just hope that Microsoft makes it easier in the future.
