Needless to say, over the last few days, we have noticed some interesting build numbers for the iPhone and iPhone 3G. It appears that AT&T and Apple are testing iPhone device software version 2.0.1, builds 5B101 (iPhone) and 5B103 (iPhone 3G). Although we are not certain of much more information than this little bit, we do know that testing began prior to the launch of device software 2.0 and the iPhone 3G on July 11th. We have also narrowed down the known test users to the San Francisco (40 mins from Cupertino) and Atlanta (HQ of AT&T Mobility) areas. Hmm.
