If I buy an unlocked Bell 9530 and use it for Rogers will the 3g work on the gsm network.

No; EDGE only. Different radio frequencies.

[Sparro]

Correct, EDGE only if using an unlocked 9530 or even 9500.

[Dubdub]

Only EDGE. Make sure you read the yellow sticky at the top on how to get the 9530 working on ATT and/or TMO. Probably some good suggestions for Rogers as well.
