i found an issue (introduced with the l2_hsic/wakelock patch) which causes LTE to not stick on reboot (requiring network mode toggle to get it back), and some other bizarre behavior when operating with wifi (shifting to 1x evdo, etc) while testing against CM10.
I've sorted this now and will upload new builds (hopefully before i go on vaca).
I'm going to assume the folks on hspa+/hspa/edge have no issue at all? Connection stays during idle, no wacky behavior, etc, etc?
Please speak now, as the change is only for lte tab but I can open it up to encompass all if need be.
