Installing Google Maps 3.3 on ADP1

Recently Google pushed Google Maps 3.3 to Android market. But due to a signature mismatch, you can not install it directly from market. It would give you signature mismatch error. If you are owing a ADP1, you should not have problems with getting your hands dirty. Here are the instructions that you can use to install new version of Maps.

Connect your ADP1 to your PC using the USB flashing cable and them perform following steps. Login into the phone using following steps.

1. $ adb shell
2. $ su

Now erase the old instance of Maps.

1) Mount /system read/write; as root on the phone:
    mount -o remount,rw /dev/block/mtdblock3 /system

2) erase the standard system Maps.apk; as root on the phone:
    rm /system/app/Maps.apk

3) uninstall the Maps data; on your computer:
    adb uninstall com.google.android.apps.maps

4) Optional; You probably want to mount /system read-only again; as root on the phone:
    mount -o remount,ro /dev/block/mtdblock3 /system

5) You can install Google Maps from the Market as normal now.

As usual, standards disclaimers apply. Thanks to  Zinx at Google Forums for this post.
