Just found this out via Pocketnow that folks over at XDA-Developers have managed to extract and run Windows Marketplace for Windows Mobile 6.5 on Windows Mobile 6.0/6.1 devices! All you have to do is to download and install the .cab file discussed here by !Aman! (member of XDA-Developers) which will then download an update for Windows Mobile to make it ready to use on Windows Mobile 6.0/6.1 devices. This .cab file fix will also work on cooked ROMs of the recently leaked builds of Windows Mobile 6.5 Build 230XX and 234XX branch.
Windows Marketplace for Mobile was officially rolled out today by Microsoft just in time for the launch of Windows Mobile 6.5 powered devices. Windows Marketplace for Mobile will also be made available for older devices with Windows Mobile 6.0/6.1 some time next month.
