We had a bad feeling that when the Skype Mobile app for Android was updated late last night and seemingly allowed calls over Wifi, things were a little too good to be true. And sure enough, they were. At left here is the original description for Version 184.108.40.206, which tells of "Simultaneous Wifi & 3G." That would have been a big deal because the app so far had only worked over Verizon 3G, forcing you to use its data connection, which of course you're paying for. And that, of course, is ridiculous, though you can see Verizon's intent -- it keeps you from buying an unactivated phone and using it as a Wifi VOIP phone when instead you could be burning through your monthly data allotment.
But lo and behold, we have a couple of unactivated Verizon phones here, and sure enough, they freak out when you try to use the updated Skype client. And just a few hours after the initial update, the app description has changed to read "Wifi runs while app is on 3G." So it's just as we feared -- your Wifi connection remains, but you can't actually use it. Shenanigans, indeed.
Update: Skype has published details on the update. In addition to being able to maintain a Wifi connection, you get incoming caller ID, copy-paste in IMs, emoticons, country names and flags when calling internationally, and the ability to set your location as your mood message.
