How to Install a Windows Phone 7 Theme on Xperia X1 and Other Windows Mobile Phones
It isn’t quite installing Windows Phone 7, but adding a theme certainly makes your phone look like it, and as we all know, appearances count.
To get started with this radical overhaul of your current (old) Windows Mobile phone, head to ThrottleLauncher.com where you will find a download link for ThrottleLauncher, the tool that makes all of this possible (select version 1.1.10 or later). ThrottleLauncher requires 5 MB of space on your phone or storage card, 8 MB of main memory to run and .NET Compact Framework 3.5 for the best performance.
Once downloaded, copy the file to your WM device, head to Start > Explorer and find the CAB file, which you should select to run and install the application. Remember to restart your phone after installing.
With ThrottleLauncher itself installed, you will need to then find the theme that you can use to make your Xperia or other WinMo device look like a Windows Phone 7!
This can be found at 1800PocketPC.com, and is titled Windows Phone 7 Suite for ThrottleLauncher. As you can see from the screenshots, the theme replicates the look and feel of the Metro UI that has made Microsoft’s new mobile platform so unmissable.
Download the theme and save it to your PC; unzip the contents and then copy the WindowsPhone7_1.2 folder to your Windows Mobile device. All you need to do then is open the theme with ThrottleLauncher and voila – a brand new Windows Phone 7 theme running on your old WM6 handset!
