AT&T announced that they will now allow VoIP apps such as Skype and Vonage to operate over their 3G networks. This means that iPhone users will finally have the full functionality of their VoIP services even when not near a Wi-Fi connection. Though it’s not official, it seems pretty clear to those who’ve been following the AT&T/Apple/Google/FCC story for the past few months that this move is likely in direct response to the FCC taking a closer look at what the wireless carrier is and is not allowing to go on over its network and whether these decisions constitute a reason for the government to be concerned. Now that VoIP has the green light over 3G, how long do you think before we get the official announcement that the Google Voice app has been approved? As much as this makes VoIP services happy, it may make AT&T wireless users unhappy. The carrier’s 3G network is already overtaxed in some areas. Will it get worse when people start doing more than just surfing the Web or updating Twitter?
