what manufacturing date should i look for if i what a new box?

i know april is good but mid june is safe to right?

thx

to be on the safe side get don't get anything past early june, so june 12 or so some say up to the 19.

On or before June 18 2009.
Make sure it hasn't been refurbished or anything otherwise it may already have the update that kills the exploit.

i got a pro 60gb 7363 dash that was made 2009-06-10.

what motherboard do i have?

jasper? what size nand?

thx

I would bet just about anything that you have a Jasper 16MB NAND since it's a pro unit.
