Hi.
I got my dev phone two days ago.
I like it very much and use it with my t-mobile complete option, which i signed for getting an iPhone 3G here in germany.
Now i have some questions on the dev phone from google.

1) am i able to flash the RC30 firmware on the device?
if yes: 1a) is my phone still unlocked?
1b) can i still use it for debugging when connected to my mac coding with eclipse?
2) if flashing RC30 on it, is there a way back to the developer version?
3) where to get the developer firmware?

Thanks a lot for your help.

does nobody have any info for me?
