you need to jailbreak your iPhone and then toggle off data with SB Settings, with an ATT sim card you can't edit the APN, so it forces you to use data.
Remember though, ATT can see that you are using an iPhone and will start charging you for iPhone data even if you have data turned off. It goes through your IMEI.
