Whoever said the Bionic isnt an LTE device is a moron. ALL the marketing for it has been that it IS an LTE device. That's the big selling point of it, it will the the first dual core LTE device for Verizon.
As for crappy Charge, yes... It's got some big issues that I tried to work with Verizon on and they told me to shove it. Thanks! I pay outrageous prices for a service and even more for your crap phone and I get what? Nice
For the GPS, something that helped me, SOME, not a ton, but some... Download and install "GPSfix" from the market. It will use a little battery because it polls the satellites every so often, but it has helped MASSIVELY with getting a signal. I still have issues from time to time, but it has made it about 80% better.
