OK totally excellent info Erik thanks. (You MIT alums beat us CMU alums
sometimes I guess.) The openmoko people definately need to address this
stuff. A couple questions inline,

Is there really such a thing as a "data plan card" ? I can't find that
on the gophone section of the cingular site. It only lists:
$15 30 days
$25 90 days
$50 90 days
$75 90 days
$100 365 days

I have a feeling that both tmobile and cingular are going to do whatever
they can to prohibit the openmoko phones. And I'm thinking the cheaper
"smartphone" data plans will only work on cingular's devices, right?
Like the device has to do something in order to be able to make use of
it- some technical limitation? Otherwise I don't know why cingular
sells two different plans, the "smartphone 5mb" is $9.99 and the "Data
Connect 5MB" is $19.99. I don't get how else they'd be different. Would
the neo be compatible with both? Who knows? I hope someone from the
openmoko project reads this thread.

OK, you're saying no matter what plan I sign up for with cingular, even
prepaid, I have to buy a phone from them too, right? I can't like, go
on ebay and buy a cheap used phone and still sign up with cingular, even
The one useful piece of info I may have then, is to tell you about the
service I have now. I have ecallplus.com, which resells cingular. They
have a few GSM plans, and you can bring your own phone... So if your
sprint phone breaks you may have a cheaper path to GSM through them for
