It also helps if you find out what carrier they have and which curve they are upgrading to. You assuming that the question was posted in the correct forum, and then assuming that the OP would use sprint(many carriers have the 8330) and describing how sprint handles sending pics can throw the whole topic out of whack. Most carriers do not handle sending pics via BB the way sprint does with picture mail. Alltel's 8330 allows sending pics just like a normal MMS or via email, yet the alltel 8130 is restricted to email only, no MMS option.
If the OP has an 8100 and they are "upgrading" then they won't be getting an 8330 since you can't "upgrade" from a GSM 8100 to a CDMA 8330 without switching carriers.
There are many variables. But it is always best to find out details about Carrier and confirm device model even before you give an answer at all
