Comment @gmail.com has always worked anyway... (Score 1) 48
I've had an @googlemail.co.uk address for a long while, and if you sent mail to youraddress@gmail.com instead of youraddress@googlemail.co.uk you always ended up receiving the mail fine.
The only difference for UK people wishing to 'convert' their email address to @gmail.com is what's displayed on the gmail.com site when you log in.
