Maybe you should read it.
[Radio] [Leak] [6-16-11] MR2.5 Radio - 1.39.00.0528w, 0.01.69.0602w_1 - xda-developers
It's been running good for me. No reboot or weird fc's. LTE speeds are solid. Haven't had a 3g handoff so I'm not sure about that. God locks are instant still. Battery seems to be the same. Averaging 9 to 10 hours with moderate use.
Sorry if this has already been answered.
What happens if I update my non-root TB with the non-root version then Verizon releases the real MR2?
What happens if the answer is nothing and then, after a period of time they release MR3, will that update OTA?
