Yes, it certainly seems that way, according to this GSMStunts.nl story. The T-Mobile SDA is gradually weaving its’ way across Europe, and will be available in the Netherlands later this month.
The handset is free on the “Relax 300” package and above, and a translated version of the article can be found here (BabelFish).
