Here's my situation. Data drops first occurred about a week ago, I was running RBJ and Harsh kernel with hsic fix in. Mainly it happens when exiting wifi range. Went back to nandroid with RBJ/Bricked and it was fine. Tried harsh again issue reappeared. Tried flashing pre hsic kernels and problem persisted. Full wipe, dirty flashes, different kernels etc. Problem is still there intermittently. Now I'm running stock everything and it seems ok for now, but I did experience it once. I guess more testing is needed. I'd think it could be carrier issues, especially as Orange UK confirmed they are having problems at (that would include T-Mobile) but my wife is on the same carrier and doesn't seem to have this problem.
So what you say? What rom/kernel combo you had issue on and on which one you didn't? Can anyone see a pattern?
