Update: Make sure to hit the "Read" link for full details on how the shutdown will affect customers (i.e. can I keep my phone? my contacts? all that freakin' digital schwag I switched carriers to buy?). Interestingly enough, the main Amp'd page is still buzzing along as if nothing was wrong, and it actually took us quite a few minutes to locate the tiny graphic linking to the FAQ.
