Hey dude! When your order shipped did you get a confirmation email?You might have to update your FW to get the sd card update if you havent already done so. Then you need format your sd card using the exfat format to let you use files bigger then 4gb. i heard you can get the sd card update without updating but it looked like a long thing to do.
My SX Pro should finally be arriving today
Mine says complete and I have Royal Mail tracking but it just syaa that it's "Expected" since Sunday.
