Because cell phones blow more calls than those j-holes who reffed Super Bowl XL, buy yourself some Cel-Fi: a years-in-the-making signal repeater from SoCal firm Nextivity, it boosts 3 & 4G data service signals up to four times their paltry, unassisted strength.
How It Works: Place the window unit near the strongest signal (which will probably be near a window), and it'll communicate directly with the tower, while the coverage unit goes in the middle of the dwelling to spread the signal evenly as it continuously adjusts to avoid grain and noise; then, pick anywhere in a 13000sqft area to do what John Daly does: enjoy five bars all day long.
What's So Freaking Awesome About It: By not making the phone constantly search for more bars, the battery life's extended. Also, when 4G becomes the norm, it'll switch over to it, and anyone capable of tethering phone to computer will be able to use this instead of their WiFi -- so the same thing you make booty calls on will provide a totally redtubular time when those calls are rejected.
They're starting off with T-Mobile and'll soon expand to other networks; you can get $100 off by entering "5bars" when you check out, and there's a money-back guarantee -- something the XL officiating crew keeps on refusing you, no matter how many angry five-bar text messages you send to umpire Garth DeFelice.
