My question is: is there any way to disguise my PC tethering so that Straight Talk or AT&T won't detect it? I assume traffic from my PC appears differently to traffic originating from my phone, so it's detectable. Is there a special browser or Firefox addon or something that I can use that will disguise my traffic? Is there some Windows networking tool that can disguise it to look like phone traffic (preferable)? I use Windows 7 Ultimate x64 and Firefox, but I have Chrome available.
I tether responsibly imo. I believe Straight Talk allows around 2.5GB of full speed data per month and then throttles after that. I've never used more than 500MB on the phone itself. I won't be downloading large files like movies or music or streaming anything. I just need web surfing and email, and possibly the ability to play an MMO if there is a way to disguise that with a networking tool and latency isn't an issue. MMO traffic doesn't consume a large amount of data, but I can do without gaming if it ends up consuming too much bandwidth. I plan to keep it under 2.5GB regardless.
EDIT: I have an 11 pin (GS4 compatible) MHL adapter on the way from Amazon. I also have a USB OTG cable that I can connect to my phone that enables me to connect a mouse and keyboard if I want. I don't know of any way to connect both the OTG cable and the MHL at the some time though. If I could do that, I could throw my phone display to the TV and navigate with a keyboard and mouse, which would be "acceptable" for web surfing until I get Uverse.
