Did you change the settings in network menu?That new build runs pretty great. Been running it since yesterday and seems as though everything is working.
Edit.. After a bit more testing it looks like data may be a bit wonky. Normally I'm getting LTE dropping back to HSPA+ occasionally.
On the latest build it wants to hang out on HSPA and briefly jumps up to HSPA+ occasionally. Have yet to see Lte.
