I work in a building with horrific reception; often I'll get all my texts at the end of the day when I leave the building. I was having a hard time finding anything recent on the connectivity of current models. Since I don't spend much time at my desk, it would be nice if my wife who's at home with our 3 month old had a reliable way to reach me during the day. Bonus points if you know of any actual testing that's been done (i.e. if I have something more reliable to go on than anecdotal personal experience)
