Sprint data network contact?

[Stephen Lau <steve () grommit com>]

I'm trying to find a contact for someone who might know something about 
the proxies running on Sprint's data network.  Basically our Android app 
uses a local http server to serve content to the Android media player, 
i.e. listening via 127.0.0.1.  Unfortunately, a system update that 
Sprint pushed last week seems to enforce a Sprint proxy 
(pd.vog.sprintpcs.com:8085) on all HTTP & RTSP traffic... including 
traffic to 127.0.0.1, which as you can imagine, predictably fails.

The EVO is our most popular Android device amongst our subscribers, and 
we're rapidly losing subscribers because of this problem.  This breaks 
streaming for many Android apps that have to use a local content server 
(for a variety of reasons, some for playing encrypted content like 
ourselves, others who need to maintain backwards compatibility with <2.2 
Android which lacked RTSP streaming).

I'm running into brick walls so far and hoping that someone in NANOG 
might know a responsible network engineer at Sprint who could help 
resolve the issue quickly?

cheers,
steve
