Quick reply to a couple of your questions.
At this point you are done using RSDlite, unless for some reason you need to sbf again. If you are able to use the phone on tmobile currently, all the radio unlock process is done. From page 1 of this forum then, all that is left for you to do is to
Put D2G-608-Kernel.zip in SD card (root directory)
Unzip D2G-608-nandroid.zip, put the folder "2011-10-188.8.131.52" in your SD card: /clockworkmod/backup (the folder should be named either "2011-10-184.108.40.206" or gingerbread rooted, depending on which version you got. In that folder you should have several .img files. If they are in another subdirectory inside that folder, they are too deep. The unzip process should be done on your computer before copying to the sd card.
Now from page 1 again, you have part of the steps left to do, and they are all done from the clockworkmod recovery screen (except starting bootstrap recovery of course).
4. Go to Bootstrap recovery, (you already have band unlocked, so don't need to flash the band unlock)
5. Flash D2G-608-Kernel.zip, after that, do not reboot!!! (this is done with the install zip option)
6. Restore D2G-608-nandroid. (thru the backup and restore, restore option)
7. Wipe data/cache/dalvik. (wipe data and wipe cache are on the first screen, wipe dalvic cache is under the advanced menu)
8. Reboot, all done.
Hope this helps clear things up.

Per Boster27, this does help with enabling data when using a sim-interposer. at
he mentions, and I quote: "I am one of the (un)lucky owners of a non-unlockable D2G. I was able to use it to make calls with a SIM interposer (i-smartsim), but wasn't able to get data working on the 850Mhz band (900Mhz worked fine on EDGE, with another carrier). After following this how-to, now I get full speed 3G (H+) on my "locked" D2G using i-smartsim!
I know that I shouldn't use data with the interposer, that it will probably burn out, but I just feel better knowing that I can use data now if I need to"
I don't know what carrier he is on, and don't know if this would work with US carriers, but is something that could be tried if one was desperate.
