'[EE] Cellular Baseband chips?'

This is starting to bug me, I've been hunting around to see if I could
find a GSM cellular baseband chip that a hobbyist can obtain.  It
seems every outfit I reach(tried Freescale, NXP and TI thus far), will
only sell to high-volume OEMs.  There's the OpenMoko project, but it
looks like the hardware isn't open - only the software.

Does anyone know of a maker of these chips who will sell hobbyist quantities?

You will NEVER find one.
These chips are VERY complex, and require lots of engineering support.
You are not worth the expense for the sale of a few dozens or even hundreds
of chips.

And you would have to sign NDA's to get any significant technical information,
and you don't have enough assets to make it worth their risk of your possibly
disclosing proprietary information to competitors.

In other words, it ain't gonna happen..

I am looking at the $15 cell phones that one can buy at Target......

Sad, tho I'm not surprised.  Wifi chips are all in the same category -
i.e. categorically Not Available To You.  Unsurprisingly I'm now running
into it for HD-level video processing chips.  I was just at a
Cornell-sponsored new business models/directions in the wireless
industry gathering, and a senior Intel guy was there discussing WiMax,
and he said Intel's wimax chips will be readily available in small qty
through "technical distributors", not sure what that means exactly but
you will be able to get just a few.  That'll make some neat novel stuff
possible in a year or so.

Could you use a GSM module instead?
Just came across a vendor website (they sell PICkit 2 and ICD2 clones
so that I got to know the name). I do not buy anything on eBay so that
I do not know how good the vendor is.

This page gives some ideas to get Wifi modules and
GSM modules, for example, Wifi modules from Gumstix.

It seems some small vendors are indeed getting them but I am
not so sure how they get it. Maybe talking to your friend in
some distributors will help.
