The last useful call I had was with T-Mobile earlier on, when the guy refused to give me any shipping details, but said that, having looked at the order, I should expect to receive my handset "very soon." When I pushed him on it and asked if that meant tomorrow, he said that he wouldn't promise anything, as "people are posting so much stuff on forums, and if I say it's coming tomorrow and it doesn't, you'll be complaining about it." I asked if I should read between the lines and expect it tomorrow, to which he replied "you'll be receiving your handset very soon."
Still no text or email though!
