Hello everyone, I have one question thats really been bugging me because I can't seem to find it any where over the internet. My question is, Can i totally block off Data Usage through just the phone itself? Is there any possible solutions? I want this phone, but just to have the wifi capability, I do not want any expensive data charges. If this phone is not possible to do so, I know some are, but I do not know which. How about the Htc Touch Diamond? Or any other phones you guys possibly know of that can disable the data function.
