Nice, from where?
At Walmart here in Canada you can't see the serial number because all the ds are behind in the back, like you have to go ask the guy to open the glass and he choose it for you.
Just got 4.4.0-10U XL black/red
Code : SW1232XXXXX
Bought at bestbuy, i could look at the codes from the glasses and they were all under 1280XXXX
Should i update it to 4,5 or don't touch anything until i receive my flash card ?
