I have to disagree, this phone was sold as a GSM phone
I would expect OM to warranty hardware defects. A DIY fix is acceptable as long
as it doesn't require special tools or create potential to do more damage. I
would much rather have OM ship me a replacement part than have to send the
phone back.

The warranty is essentially non-existent.
It's supposedly 14 days D.O.A.. Dead On Arrival, in its strictest
definition, means that as long as the phone boots up, that's it. It doesn't
matter if it's not really functional. As long as it boots up, it's
technically not DOA.
If it can't make phone
I feel mislead by their marketing, which led me (and, from what I've been
reading, many others) to think that the phone was actually ready for both
developers AND regular folks. This, of course, is false, as it can't even
connect to the internet *out of the box*, and requires a ridiculous
think they should have put a big warning page during the
purchasing process before it takes your credit card, so no one would
have an excuse to complain.
