We are AT&T and grandfathered into unlimited data for $30 per month. My IT person said to drop to the 2 GB plan and save $5 per month. he said none of our users ever exceeded 2 GB and few exceeded 1 GB of data. Thoughts? I talked to our company AT&T rep. He said the same and that if you go over AT&T automatically adds 1 GB for $10 more. He also said you get multiple warnings as you approach your limit. My Blackberry has never done 1 GB but the wife's iPhone 3GS averages over 800 MB and has gone to 1.2 GB once. Looks to me on my account that saving $60 per year would be smart but I will likely move to an iPhone next year when the real 5 arrives. Once you give up unlimited, it is gone. For my wife, if I give it up we save $60 per year. Even if she uses more one month, we still save $50. I am tempted. We do not do movies or much music. However, She may start using iCloud and could move over two thousand pictures there. After the initial move, I believe her data transfer to the cloud will not be all that much. Am thinking of staying unlimited for first 90 days to see how the 4S uses data. After that will likely move one number to the 2 GB cap. What are you all doing?
