Just to share information:
on my 1.1.2 BL 4.6 iPhone the World Clock seems to have a new years bug, since local time in Wellington, NZ stays at 07/12/31 although it's already new year down under. we will see, how the rest of the world develops.
This might be a reason for an new Fimware to come out today, because all world clocks will stay in 2007 (wild guess ). nevertheless happy new year everybody
