XAP Installer is a must installed application for Windows Phone 7 HTC HD2 users like me that cannot get activation code from Microsoft. However, installing XAP application one by one is a painful task. Luckily, with Tom XAP Installer v1.2, we can select multiple XAPs and install them with 1 single click. Perfect to use after installing new WP7 ROM.
Tom XAP Installer
Tom XAP Installer requires unlocked Windows Phone 7 device, Windows PC with Microsoft .NET Framework 4 and Windows Phone SDK. Make sure that your phone was connected to PC with Zune launched. And phone is not in sleep mode.
