Just got my new phone today,

Changed the date as instructed which is perfect. But when I receive texts it comes up with a 2043 date.

Cannot find anyway of changing it, as the normal date/time is correct

Any Ideas

Did you try a battery pull to see if that resolved it?

There is no such BlackBerry as the 9990. What BlackBerry do you have?

There seems to be a few of these "9990's" out there. Maybe that's a non-bricking replacement for the 9900. LOL
