Hello everyone, I've been looking and looking and trying to find answer. I just jailbroke and unlocked an iPhone 3G. My friend has an T-Mobile plan without data. Data isn't too important for her as she in around Wifi for most of her days. I swapped out the Sim card and the iphone recognized it fine. When she is off Wifi, and clicks on Safari it brings up a site that says you do not have data on your plan, you will be charged $1.95 a MB if you hit continue and accept the terms. My question is as long as she doesn't hit continue she should be ok correct? Apps like weather would not load if only on Edge, I assuming no data wont allow her to get anything. I just don't want her to receive some bill with $$$$ worth or charges from apps going out and trying to receive data. Is there a place where i can completely disable any ability to go out for data, and only get wifi. One last thing, is MMS part of data? I read that in a few of the threads. I also read MMS wasn't working on iphone with T-Mobile. Any answers to these questions would be great. Thanks.
