The delay could be due to some less than favorable feedback that Nokia received from some of the 300 people who were lucky enough to get a pre-production model. So far, no U.S. carrier has decided to offer the unit although we have previously reported that T-Mobile could bring a subsidized N900 to the U.S. as part of its' "Project Dark" cellular makeover. Currently, an unlocked model is available for pre-order at Nokia stores and on its' online store. The Maemo powered device has spectacular internet capabilities as we noted in our preview of the N900. It offers full flash support and as we wrote, "We wish all smartphones had such a browser".
