Last week we covered the possibility that the iPhone would get a hybrid chip allowing it to work on CDMA and UTMS carriers (like Verzion and AT&T) simultaneously. Today, Appleinsider is citing industry analyst Ashok Kumar who says that such a chip hasn't reached field trial status, and that the lead time required for this type of device makes him think consumers won't see it in 2010. Kumar goes on to suggest that this new "worldmode" chip would be more likely to show up in 2011.
While it would be ideal for Apple to have one model of iPhone that would work on nearly all wireless providers in the world, the technology just doesn't appear to be there at this point. Kumar points out that even though the hardware is in development, the software necessary for the basebands of such devices doesn't even exist yet but would get there eventually.
So that's one vote against a 2010 debut for the Verizon iPhone, despite the corroborating rumors from other supply chain analysts. As eager as everyone is for an alternative to AT&T in the USA, I don't think this is the last we'll hear of the story.
