Well, next step: connect the "Neo900" modem to the GTA04 USB, et voila: a veritable Neo900 prototyping setup, consisting of DM3730 and all, connected to PHS8 modem via USB, (almost) exactly like we'll see it in final Neo900. Arguable if a N900 would beat the GTA04, due to the hw kbd, or the GTA04 wins thanks to the DM3730 instead of N900's OMAP3530
