How to force move all apps to your sd card

You’ll need you device driver installed (or at least the drivers that come with HTC Sync) and ADB (Android

Debug Bridge) or the Android SDK. The SDK itself is a >100MB download and can
be relatively difficult to install, however if you head here, look under the section entitled Mini SDK, click show,
you can download a zip file called SDK-Tools.zip. Once downloaded, extract the
contents of that folder to a folder of your choosing. I recommend somewhere
easy, like C:\Android\ as you’ll need to navigate to it via a command prompt
later.

You’ll also need to enable USB Debugging on your phone. that’s
easily enough done by heading to Settings -> Applications ->
Development -> USB Debugging. You’ll get a warning message, but just ok
that you’ll be fine.

Once you’ve done all the above, the process is as
follows:

1. Connect the Phone to the PC in Charge Only mode
2. Open a
command prompt (Start -> Run -> CMD, you’ll need to run as
Administrator)
3. Navigate to the folder you extracted ADB to. In my case,
the command would be “cd\Android” (minus the quotes).
4. Type adb devices and
press enter. You should then see the serial number of your phone displayed on
screen. If you don’t check, that USB Debugging is enabled and you’re connected
in Charge Only Mode.
5. Type adb shell, press enter.
6. Type pm
setInstallLocation 2 press enter (it’s important you enter this exactly as
written as it’s case sensitive)
7. Type Exit, then disconnect your
phone.
8. PROFIT! 

You can now
move apps that are already on the handset to the SD Card. Head to Settings
-> Applications -> Manage Applications -> All -> Click an app ->
Move to SD Card. All new apps will also install to the SD Card by
default.

It’s worth mentioning that apps with active widgets cannot be
moved. Also, a certain portion app will remain on the phones data partition, but
this goes a long way to assist with the lack of internal memory!
