Windows Phone 8.1 Requires Class 6 micro SD Card, Class 10 Recommended

We are only few days from release of WP8.1 update and one of the upcoming features will be the ability install and run applications from micro SD card if the developer allows it. However, new rumors indicate that MS has set some specific requirements for the use of micro SD cards.

Starting windows phone 8.1, you will be required to use minimum of Class 6 SDHC card but the company recommends Class 10 minimum. So if you using one of those cheap Class 4 cards, you will not be able to use them.
