There seems to be a lot of confusion about how do this. Actually it’s pretty easy:

  1. Reboot your machine and hold down CMD+R.
  2. Choose the option relating to Disk Utility and erase the Macintosh HD.
  3. Close Disk Utility and from the list of options, reinstall Lion.

(Note, you’ll need to hook up your machine to a wifi Hotspot so that it can download the entire Lion image from the internet…zzzzzzz)

I simply applied the same technique to my Nexus S and have reproduced the steps below for my own future benefit.

[Notice! You must have root access on your Nexus One / Nexus S.]

1. Download sqlite3, which comes with SuperOneClickv1.7-ShortFuse, and copy it to your SD card.

2. Connect your phone to your computer. Open a Command Prompt, and type the following commands:

adb shell
$ su
# mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
# dd if=/sdcard/sqlite3 of=/system/bin/sqlite3
# chmod 4755 /system/bin/sqlite3
# mount -o remount,ro -t yaffs2 /dev/block/mtdblock3 /system

Done! Now you can use sqlite3 to examine database on your Nexus One / Nexus S from a Remote Shell or even from an Android Terminal Emulator.
