Discussion on:

Five apps that put the 'phone' in 'smartphone'

My main objection to unwanted incoming calls is that the service provider gets to charge me for it. I can blow off an abuser myself, either verbally or by looking at the CID, but ATT still gets both his dime and mine.

So will Call Guard keep them from charging me for these calls? If not, I see no use for it.

Really, if you're going to write an article about apps only for the Android market, ya think maybe you should mention that in the article title, hmmm?

at least on at&t it does.
I am usually connected to wi-fi on my android phone, so i figured "use google voice to make calls, free for US calls, right?"
well, after getting a txt from at&t about my talk usage and checking the bill (all plan minutes and rollover minutes used up, with a lot of overage), i called at&t.
the agent i talked to said they are familiar with google voice, and at&t phones will not make voice calls over data connection - 3g or wi-fi.
i did not find reference to this in any of the google voice documentation

at least at&t was good enough to credit my account the overage, and give me some free rollover minutes back after i explained what had happened.
