I just returned my G1. Nice phone for the most part, but two things about
it killed the deal.

1) T-Mobile will not ring my phone for more than 30 seconds. When
connect time is subtracted this means that I get an average of 2.5
rings before the caller is forwarded to T-Mobile's voicemail network.
Problem is I can't always answer the phone in that time.

I tried having them disable voicemail but then the phone failed-over after
15 seconds. Compounding this hassle, callers always got a T-Mobile
network message. Spent 2 painful hours on the phone with support
(3 calls, 5 transfers, 45m on hold) and I finally reached a tech with
"7 years" experience who said they cannot ring my phone more than 30
seconds and will always fail over to a T-Mobile announcement regardless
of any settings.

You have to wonder what the logic to this is. Verizon rings for 60 seconds
before going to busy (or voicemail, if enabled). Why would T-Mobile piss
away perfectly good new customers for something like this?

2) The G1 will not play mp3s over bluetooth, not even in mono.

Surely HTC/Google doesn't think my train mates appreciate having to
listen to someone else's mp3s over tinny handheld speakers, unable to
do something as simple as connect to a Jabra headphone... (at least it
works for calls).
