The speculation can finally end on the i907! No, it’s not the AT&T Omnia.
With a deviation from their usual naming conventions, the Samsung SGH-i907 will be the US version of the i780 as reported by BGR. This could mark huge competition for the Treo Pro, especially if it comes with more memory than 128MB, plus a nice subsidized price tag (of around $199). Not enough RAM and a high price are the biggest complaints about the Treo Pro.
