A correspondent notes that Amtrak's waiting room at Penn Station has AT&T Wireless's Wi-Fi active: He writes, the splashpage finally arrived at the Amtrak waiting-room at Penn Station. After filling in the personal info ( they have the nerve to ask for the last four digits of your SS number!)... He was on a PDA and the page failed to allow him to purchase a connection. A call to AT&T Wireless Wi-Fi was a waste of time, the lady I talked to was clueless. The funny part is that I got far enough into the process to receive an 'Thank you for registering for the AT&T Wireless e-Wallet' e-mail.
The correspondent notes, There's a Starbucks at the other end of the station (I have an account with them) and hopefully the McDonald's also in the station will work again soon. And then Verizon which works from the McDonald's on 7th Ave. if you sit close enough to the front window.
