It's the MicroCell thing that AT&T is selling/giving away if you already have all the crap required to make it work. It's a mini tower in a sense for your house. gives me 5 bars all over the house. It's supposedly VoIP but I haven't researched it enough to verify because most of the boneheads at the stores have no idea about the products they're selling.

how much is that? can you get it for free?

There is a way to get it free.
But we got it for free because I already have unlimited minutes (I like to talk ;-D) and U-verse 450 and because they made us wait for 45 minutes to ask some questions. Dugie showed them a bit o' temper! She hadn't had anything to eat all day and it was 3:30. She was ready to tear someones head off by the time we were called.

All you guys think she's so sweet. There is another side to avoid. :p
