i am using the ORANGE UK .52, anyone else finding UMA works for phone calls but not e-mails?? i have not tried to send e-mails using UMA yet, but i do know that when i have wi-fi connected i do not receive e-mails unless i have cellular service as well. i have very limited cell reception at my house so i use UMA and have not been receiving e-mails until i get cell reception. might be another bug....
