Well, my data connection is really misbehaving now.
I did two things - well three
(1) 3.3 rom
(2) 1.27 radio
Both of those were done last friday, and honestly the thing has been behaving just fine since then... until yesterday when I
(3) changed the Slot Index to get faster rings (

Since (3) it seems my data connection has been wonky - as the OP says, it will either just drop the arrows at random (or, if I force allways on per this topic, it will get itself hung up) and it won't reconnect without a radio reset (flight mode, or soft reset)
I will try today leaving the slot index setting in place but reverting to the 1.12 radio firmware, run it for a while that way, and if that clears it up wonderful. If not, I'll try the other combo (1.27 radio and revert to Slot Index 2 setting)
