I've been feverishly checking my phone for the 4.3 update but have yet to receive it. I would think it would have been pushed to the whole of sprints customer base by now right?:'(
Couldn't you just clear data/force close the Google frameworks app then check for update? I've done that without any problems on some of my other devices. May take a few tries but usually works
OTAs can take days, even a few weeks for everyone to get it. I have never gotten an OTA on the first day of rollout unless I downloaded it from the internet and installed it myself, iow, don't hold your breath.
Last night about 0200 I checked for the update; nothing. I cleared the framework again (as I had done many times before in the past 10 days), and suddenly there was the update. It took forever to download it (slow WiFi where I was), but the installation of the update was only ~10 min. No problems so far. Plus, it has fixed the roaming guard issue that I have had from Day 1.
