If you have a phone with camera, you don’t need to read this any further. This is more for users with blackberries (because I own a Blackberry Curve).
Facebook has a rule that you cannot upload mobile pics by emails, only from your phone but alas, blackberries can send emails. So, if you have been trying to send pics from your blackberry, Facebook will send you a confirmation code each time. Which eventually becomes annoying.
To prevent from getting confirmation codes over and over, you need to use MMS feature on your blackberry and send pics through that. Voila! no more confirmation codes! this is because the address comes in the form of phone number or phone number directory, not email address, which Facebook obviously likes better. Happy uploading. :-)
