Sprint TP2 gprs sms hack?

[stevedensmore]

If you go to settings > connections > advanced network, then click the SMS Service tab. You can select whether or not to do SMS over GPRS or GSM. I try to make it GPRS Preferred, but every time I reset the phone it goes back to GSM. Is there a hack that will make the setting stick?
