Tired of AT&T's spotty service at your home or office? Well, you've got two options: ditch your iPhone and move to another carrier, or pick up an AT&T 3G MicroCell ($150). This nifty little box acts like a mini-cell tower, routing your calls over your broadband Internet connection, and ensuring full coverage for up to four connected devices. For you long-winded users, the company is also offering a $20/mo unlimited MicroCell calling plan, but otherwise you'll simply use your current calling plan minutes.
