Do you have sim-card on your phone? If you have it is an Gsm-phone. If not it is CDMA.

If you wanna know more about the difference between GSM and CDMA, you can visit this site:

For short, your phone is GSM, so you SHOULD NOT upgrade your Diamond with a CDMA rom.

let's see if i get this right, since i got a sim-card that i can use in any phone i want to and still have the other phone activated, it's not CDMA? or am i completely out and nothing near the real thing about CDMA? oO

Quite simply, GSM and CDMA are two different types of networks. Likewise, the GSM and CDMA Diamonds are two different phones.
