Quick question all, can I use an iPhone 3gs without a data plan? Is there any way to do this? I know AT&T used to scan the network and add a data plan to any smartphone. Not sure if they still do this. My mom's line has a dumbphone, which is malfunctioning due to water damage. And since I already have an iPhone 3gs sitting around, I figured I can put it to good use. But of course I don't want to pay for a data plan she wouldn't know how to use.
