Good point. Part 15 too. But I think they could do the re-testing very 
quickly using their contract labs, and then the only hold-up is getting 
the FCC to sign off on the changes.

On Part 15, you can get away with minor changes pretty easily if you can 
show that they will have no effect on EMI. I've taken many products 
through part 15 certification. It's no fun, but the FCC is not 
unreasonable, and readily accepts changes from reputable testing labs.

Interesting that the testing for phones does not seem to ever involve 
the phone being held, though this is the first cell phone that ever was 
designed with the expectation that the user would be touching the 
antenna during use and no one at the FCC ever thought such a thing would 
happen so they never thought to ever require that sort of test.
