Here's the fix:
1) Dial ##3282#
2) Choose Edit Mode
3) Enter MSL
4) Choose Advanced
5) Change HTTP PD Proxy Port to: 0
6) Change HTTP PD Proxy Address to: 0.0.0.0
These are the settings for other Android devices so I do not know why Sprint changed them. But this will get your streaming services working again.
3.70 update killed your streaming music? Here's the fix. - SprintUsers.com
