I don't know all the latest on the plans but T-Mobile does seem to be phasing out the Even More Plus plans (the contract free plans where you bring in your own phone). They aren't available online any more apparently, but some sources say they are still available in-store or over the phone. What many have done to get the $10 data is go to a store with a dumbphone with some basic data capability (e.g. Motorola L7 or something like that), say you want a SIM for your own phone and sign up with Even More Plus which has a $10 dumbphone data plan option. Then when you get home just pop the SIM in your N900 and you're good to go. A ~$50 total bill (w/o texting) is a really good deal for the features of the N900.
