Did anyone get an update on 4-10-15 and was able to get the actual preview insider dow and fast option? I was actually able to get the option this past Friday. I usually check it every other day and it usually said there is no preview builds for this phone. Was this GDR2 and did anybody choose either the slow or fast and what wad the outcome? It looked like the firmware # didn't change as I tried to screenshoot it before the install went through.
