which bootloader?

[Brian Wilson]

The wiki says "The latest bootloader binary builds can be found under
http://buildhost.openmoko.org/daily" but when I go there I find 12
files. I can narrow it down to these 3 based on the "gta02"
and I can guess that the vN refers to a revision of my phone. Which
phone do I have? Is it marked somewhere?

uboot-gta02v2-latest.bin
                22-Aug-2008 02:14  211K
uboot-gta02v4-latest.bin
                22-Aug-2008 02:14  211K
uboot-gta02v5-latest.bin
                22-Aug-2008 02:14  212K

I want to try Debian and first thing it says it to make sure my Uboot
is up to date.

Thanks Brian
