Can i hack the GPRS setting of an unlocked t-mobile sidekick slide, to acsess the net in Australia? - gprs sidekick hack

I bought recently an unlocked T-Mobile Sidekick Slide on the seas. I put my SIM card to Telstra and it allows me to call and msg, but I can not access the network. Is it possible to change or turn off the GPRS settings, you can use here in Australia?
