Dell has stated they will be releasing a variant for AT&T which will work on Rogers/Bell/Telus. Also claimed they will provide an update to 2.2 later this year. Speculation is Aug/Sept for a US release. The US release might have 2.2 but I would not hold my breath on that one.
Pricing from CarWarehouse is being quoted at free on 25 pound tariff, or 429 pounds outright, so this should be under $500 outright in the US. So far our brilliant Canadian carriers have not said a peep about getting it.
