Dis Guy: It might sound silly but i get very confused with the blackberry names and what they are actually manufactured as (model numbers)

My cousins want me to help him get a Bold 2/3, unfortunately i'm not used to these Bold 2, Curve 2/3/4, So i told him to get the actual number then i can check the price for him, same way my aunt wants to get a Bold 5 for her Birthday, when I ask what her the model number she said that what they are called, I am not very familiar with the numbering systems, I looked through blackberry website and carphone

Most of them look alike same with the curves , i think the only one i know quite well is the torch it has no numbers

So who can decipher which is which

Bold 9900 = ? bold 5 the best and most expensive of the lot.

Bold 9790 = ? bold 6 It came last of the bold, though cheaper than 5.

Bold 9780 = ?4

xprt.ngnr:
bold1-9000
bold2-9700
bold3-9650
bold4-9780
bold5-9930 or 9900
bold6-9790
