Verizon 4G does not do well inside buildings. My phone drops to 3G all the time at work. Its great once I get outside. Hopefully they keep 3G around forever as a fall back because it seems to work more consistently indoors.
I work in Midtown Manhattan in a room that is floor to ceiling windows. I constantly bounce between 4G and 3G. It's actually kind of annoying because it always does it when I am trying to use the browser.
My Razr Maxx does it all the time. The Galaxy Tab 10.1 was also pretty bad... only it would struggle dropping down to 3G. One of the reasons I cancelled the service on it. It was not useable because it would constantly be in limbo land between 3g and 4g.
Too bad u could not toggle to 3g only. On my thunderbolt I would just switch to CDMA when I came across that. Lee -- My opinion on religion and science? Science builds airplanes. Religion flies them into buildings.
