Hey all, So this idea JUST struck me, and despite the fact that I was able to snag NetShare, i've only really used it a few times to tether, and a lot of web pages do not open properly (for instance, MacRumors) when using Firefox through a proxy. Not to mention, tethering using the NetShare method absolutely kills the iPhone's battery. Well, my dad has a Sierra Wireless 875 AirCard, which just has a Sim card in it with an unlimited data plan...i was wondering if popping in my iPhone 3G sim card in it would work, since i already pay for unlimited data...i haven't tested it yet because i don't know if there are any special settings i would need to do to get it to work, or if i would get tagged by AT&T with usage charges. I was thinking that i could simply just buy an aircard from eBay and pop in my iPhone sim for those instances where i do need to tether and don't want to do it through my phone. Again, not sure how different this is than using the NetShare method, other than it would be MUCH more hassle-free and allow web pages to load normally...any input would be great, thanks!
