[Nexus 5 Android Development] HaiKaiDo:
So I finally got a logcat of whats happening when I try to send a MMS on my Nexus 5 on sprint. I included a few loops of the error in the hide box here. But the thing I see that stands out is

06-28 21:49:24.176 3043 5279 E Babel : java.io.IOException: Cannot establish route to /68.28.31.7

Is the / in front of the address normal? I dont think it is.

I looked in the apns-conf.xml and none of APNS have /68.28.31.7 just 68.28.31.7and no mention of sprint LTE apns.

Anyone that could take a look and offer some thoughts would be awesome.
