After reading a few posts here about people using the Treo 180 on
AT&T's GSM network I picked one up on eBay. It was a T-Mobile unit but
they gave me the unlock code. I currently have a TDMA phone on AT&T so
I picked up an AT&T sim card and unlocked the Treo. So far so good.

When I called AT&T they told me they couldn't activate it on their
network for the following reasons:

"my supervisor has never heard of it, so we won't activate it"

me- can you find someone who has heard of it

"we can activate the 270 but not the 180"

me- the only difference is a color screen

" if we did activate it would cause service problems because it
doesn't have an AWS part # on it"

me- It's a GSM device, you have a GSM network, I know others have done
it...

No matter how much I argued with her she insisted she couldn't
activate it.
Am I mistaken? I should be able to do this, right? Can anyone suggest
a strategy that might work here?

Thanks!
