When the keynote was given for Firmware 3.0, a crowd of developers applauded the dozens of features that would not only make development easier but also open up more APIs to create even more robust Apps. Consumers were lavished with just as many non development features, the biggest being the highly anticipated MMS functionality and Internet tethering. A list of carriers appeared on screen but absent from them was the biggest one of all: AT&T. some were shocked and others, not so much. The carrier has had difficulty keeping up with the data demands of iPhone users already but for something as rudimentary as multi media messaging, the texting equivalent of sending an email, there was no excuse. AT&T has dragged its feet on bringing MMS functionality to iPhone users but the big question still remains: when will tethering be officially available? We’d like to hear your take on this issue, are you considering dropping AT&T for another carrier that actually offers features most smartphone users enjoy or are you going to wait out the storm and be that much happier when MMS and tethering are enabled on your iPhone? Sound off in the comments.
