Turns out that within the documentation that comes with the X1 is a folded black paper that says “X1 Support,” and inside is a card with information on how to get in touch with a real person to ask them phone questions. Inside, it says:

The personal touch: call the X1 support number and your call will be fast tracked directly to one of our specialist teams. This is your mobile manual to go, where you can learn about all of the functions on your X1 and solve any issues you have – an extra helping hand in addition to your operator and retailer contacts.

I just tested out the service, and they really didn’t ask me for any proof that I had an X1. I went to m.sonyericsson.com/x1support and called the number there. I asked the lady on the other end how to enable the speakerphone on the X1 (as a test), and after being placed on hold for 3 minutes, she had an answer. Pretty cool. Do all Sony Ericsson phones have this?
