Flashed 3/23 this morning and I think hashcode must be close to a fix for the 4g. It picked up faster than it ever has before and has been perfectly stable since with almost full bars the whole time. ( I live in a big city) I have a few hours to waste so I"ll play around with this build for a while and report back with bugs. So 45 minutes of heavy use of 4g it only dropped once but restored itself without me having to toggle wifi or gsm. I would say any one worried about data could probably rest easy with 3/23. The camera is in the same place so only the camera works panaroma and video don't work.
