Finally something forced me to upgrade to OSX 10.5.7

I took a whole night, and still couldn't get my home grown iPhone application running on my iPod Touch yet. At first I was stuck at generating the certificate. Then I was stuck at figuring out the hardware device profile. And finally, I realized that I have to upgrade my MacOSX to 10.5.7 in order to install the iPhone SDK 3.0 (so that I can use my iPhone SDK3 device to test application).

And before I install 10.5.7, i wanted to play it safe so I am freeing up space on my harddisk in order to create a OS parition backup.

And the journey continues.
