Yesterday I got really tired of how slow my rooted Samsung Galaxy Spica I5700 was. Up until then it was so slow that I had to wait like 10 seconds before the SMS window would show up. It was rooted with LK2.08 and I had also installed SamdroidMod Kitchen. But yesterday I downloaded the latest “normal” firmware to Galaxy Spica and installed it with Odin. The installation went fine, without bricking my phone. 
And it is sooo fast now compared to LK2.08! It feels so fun to use it now. I can’t understand why the phone became so slow with my previous configuration. However, if you want to unroot your phone and/or update the firmware of your Galaxy Spica, here are some useful links:

GreenDevDroid – Black Android Samsung Spica Theme
I found an awesome looking, dark theme to Samsung Galaxy Spica i5700! I don’t know what to say else than it’s just awesome.
But the latest version (8.1) requires that you have a Spica phone running the custom ROM Samdroid v1.2.x or 1.3.1 deodexed. And to run Samdroid you must root your phone with the LK kernel. I only recommend doing these steps if you know what you are doing and are aware of the possible damages.
Root Your Samsung Galaxy Spica With LK2.08
Yesterday night I rooted my Samsung Galaxy Spica i5700 with the LK2.08 kernel from Leshak at the Samdroid forum. You can find the kernel on his forum. This kernel gives you root access to your Spica, changes the Recovery function and other stuff, you can see the full list of what the kernel includes in the opening post in the forum thread.
The only problem was that the guide in the thread, that described the steps to flash your phone, wasn’t very great. Only two steps that didn’t say much. But lucky me I found a much better guide about flashing LK2.08 to Spica on this website:
The procedure went fine for me and now I’m sitting here with a rooted Spica. I rooted my phone because I wanted to be able to get the extra functionality out of my phone. And I have always liked to hack and take stuff apart, even if this only was a simple flash procedure. I also had to root the phone to be able to change the default theme to a black one. I’m such a perfectionist with my black notification bar. 
Here are two other guides that show you how to flash your Galaxy Spica (but to 2.1). I don’t really know if they are any good, but at least they give some tips and images:

EDIT:
I found another nice guide that shows you how to root your Spica with LK2.02:
