I still don’t have Windows Phone 7 activation code from Microsoft until now (failed to get it when WP7 launched on HTC HD2, and don’t bother to get it now too). Therefore, I cannot access to Windows Marketplace officially. However, that does not stop me from testing WP7 applications because I can unlock / jailbreak WP7 and sideload apps into it. I tested on Windows Phone 7.5 build 7720 XBmod-Yuki ROM and manage to install custom applications with Multiple Xap Installer and Tom XAP Installer. Not sure this will work on other native WP7 phones or not. Try it out if you want…
