Thanks,

I will go with Telcel. Data is the primary thing I am interested in. From searching the Web it looks like this may work:

And I think these are the APN settings I may have to use:

APN: internet.itelcel.com
Username: webgprs
Password: webgprs2002
APN type: default

I think the Telcel Amigo prepaid card is what I should get for the N900, but if you have a better suggestion I am all ears....
