CTA Underground train Chicago (Red line, Blue line)
I have a BlackBerry Tour 9630 with the Everyting Data plan w/ Roaming. The network options on my phone are set to Global > Automatic, so roaming in enabled. I cannot however use my phone for calling/text or data when on the CTA underground subway system in Chicago. It shows 1X and it seems like the signal is connected, but I get message LB280 or some other kind of LB error message. The CTA subway has active ATT/Verizon/US Cellular networks and everyone can use them; even T-Mobile roams off of them and is in the progress of installing their own antennas. How can I, as a Sprint user, make/receive calls/text/data while on the CTA underground? A friend who works for Verizon told me about PRL updates on my phone, but I'm not exactly sure how that works or what it is/does?

You should be able to use your phone starting early next year. Sprint recently signed up to lease some of the wireless infrastructure in the subway. I asked some friends who have AT&T if they gets service down there, and they said yes, so hopefully Sprint will have the same kind of deal. I have the same problem where it shows me having roaming service, but nothing (internet, text, voice) works.
