I'm still not sure I trust that rumour about Ice Cream Sandwich. I think it was said recently that Google might be working with multiple partners to release Ice Cream Sandwich phones based on different platforms in roughly the same timeframe. That makes more sense to me. However it It would also make sense that the next-gen Nexus uses OMAP4 though as Google seems to be taking turns on partners for that. Maybe LG which hasn't made a Nexus yet and is already using OMAP4 in the Optimus 3D?
