Are there alternative app stores for Windows Phone 8?
This is a webapp store for Windows Phone http://www.windowsphone.com/en-us/store/app/webapps/49e97b4c-7715-4103-8519-066244fc9e2f
He was asking for an alternative app store for Windows Phone rather than Microsoft. The link you give is a Microsoft site.
But this is same original app store as Google Play is to Android apps
Microsoft does not allow alternative app stores for Windows Phone 8 apps. The closest I could fine was a site that reviewed apps and gave star ratings but took you to Microsoft's store to get the actual app. The same is true for Windows 8 and RT though of course regular Windows 8 can still use the older desktop apps. See links below for more info.
Thanks for elaborate reply
