Partion 27 is recovery, and bootloader is partition 5.
I see from the AT&T thread that many people are getting their phones this weekend. If someone who gets the phone can send me an image of the bootloader I'd like to start getting a look at it.
If you need directions on how to do this, let me know. Currently I'm trying to figure out what the block devices are on the phone. If anyone knows this let me know, so I can direct someone (dbgeek) to get a dd of it.
