Seems to have worked, the bug just got upgraded from P3 priority to P1 (the second highest priority).
Per Google, a P1 bug is defined as follows:
"An issue that needs to be addressed quickly. Such an issue significantly impacts a large percentage of users; if there is a workaround it is partial or overly painful. The impact of the issue is to a core organizational function, or fundamentally impedes another team."
I haven't actually seen my phone use B41 though, it just idles on it. As soon as I start an active data session, it switches back to n41 + B2/66. It's almost like the network is offloading idle phones onto B41.
