I am not asking about the contracts and how would i be treated by O2 if i found using GPRS on another mobile phone. I am asking those who tried it, Did you get charged for accessing internet by your iphone sim on another phone device like Blackberry or sonny erricson? I have managed to set up GPRS by the following APN, mobile.o2.co.uk and it working fine. I dont know about the money yet. Thanks. NB: I am using another phone device because the iPhone sucks as a phone.
