Well I decided to give it a shot and picked one up today. It was a challenge to get one since my local Sprint store apparently hadn't been trained on them yet and I was the first one to come in for one. Eventually they figured out how to activate it and I came home and hooked it up. After about 20 or 30 minutes it was all set up and ready to go. I did get a nice improvement in signal to the places in the house that I needed it most. As most of you know I have trouble receiving incoming calls due to the dreaded CDMA NID border. Maybe my expectations were a little too high but I didn't get as good of a signal from it as I had hoped. There were a lot of reviews going around on various forums and most people really hyped this thing up. But so far my call quality has been excellent and I haven't missed any incoming calls as the Airave has it's own NID that doesn't fluctuate. There is one minor problem involving text messages. For some reason my Rumor isn't mixing well with the Airave. If I attempt to send the same text to multiple recipients it produces an error message on the last recipient on the list. So for example if I send any message to let's say 3 people at the same time it sends fine to the first two but fails on the third. This happens every time. I believe I have narrowed it down to being an LG Rumor bug. I will post more when I get a chance to use it more and perform more tests on it.
