Nokia always give the month of product releases but never what day it will be until that month is here I've noticed from my past experience with Nokia which is plenty as i have 13 nokia devices.
after the hardware problems with 5800's first batch and the lense problems with n97 I'm happy for nokia to delay the product by a few weeks whether it be for hardware or software i don't care as long as in the end I'm getting a better product out the box.
initially its disappointing but the benefits are worth it if it means better quality
