  Extremely helpful guys, THANK YOU Anthony Cennami and Douglas Garstang for
  posting this.

  I do find it strange that Sprint specifically isn't working, but the fact
  that L3 is telling everyone to move to 1.4 or systems will fail is
  EXTREMELY useful information, thank you!

  I will start testing on 1.4.8 immediately, and I'll report back my
  findings.
