I don't know why I do it, but I keep reading these silly threads about getting caught tethering. I'm not worried about getting caught cuz I actually pay for the right to tether.
But someone mentioned that Verizon might have the ability to throttle down my bandwidth if they sense that I am using too much trafic and it occured to me that this may explain something that has bugged me for a while...totally unrelated to tethering, I might add.
I have a GPS app that I use for off roading and alpine hiking. It is called Trimble Outdoors. The app downloads map tiles as you move around. If you zoom in it has to download map tiles for that zoom level. So with 10 zoom levels you end you with 10 seperate map tiles for the same location. It stores these map tiles on the SD card so that it doesn't have to download them the next time you visit that same location like Google Maps does. And since the map tiles are stored on the SDCard you don't have to be connected to the network to use them the next time.
So in order to be prepared for off-roading where I won't have network coverage I sit in my living room panning around the state so that I have a map tile for every square foot of Nevada. I then zoom in one level and do it again. I currently have about 800 mb of data in my map tile cache directory.
I noticed that I can pan around for about 2 hours downloading tiles pretty quickly and then it slows down to a snails pace for about 15 minutes and then it just stops working. So I put the phone back on the wall charger (downloading these tiles consumes a lot of battery power). The next day I can get another two hours of zippy downloading followed by 15 minutes of sluggish downloads and then it stops again.
Is Vz throttling my bandwidth becasue they think I am downloading movies? LOL
OK...call me paranoid. But it got me to thinking. If I am paying for the rights to tether and I have an unlimited plan (130 per month)...wtf?
