Connecting Nook Color to Sprint Hotspot

[kgirl58]

Has anyone successfully done this? I get it to connect and can use the web on the Nook Color, but I can't use Barnes & Noble's Shop on the Nook Color. It simply freezes. The Nook Color is running version 1.2.0 of the software and the brand new Shift is running Android 2.3.3 (Gingerbread?). Barnes and Noble is no help because they claim that it's a router problem on the Shift. But that doesn't make sense to me because I don't understand why I'd be able to search the Web from the Nook but not use Barnes & Noble's own app. How do I even investigate/change the router on the Shift? Is that even possible?

Thanks in advance!!
