When my cable internet choked here for 2 days, I tethered my iPhone via NetShare. The speed is excellent, and apart from a slight delay connecting to each site, the difference is pretty negligible.
The problem was the battery was draining on my iPhone, while it was plugged in USB to my laptop. I'm assuming that USB can't provide enough juice, although I haven't tried tethering from a wall plug - should I expect that to be any different?
Also, the phone got pretty hot, just on the edge of being uncomfortable. to touch on the back. This was after 1-2 hours of tethering.
I haven't tried Netshare, but I noticed the same thing when using real-time GPS tracking and pulling the map data via the 3G network while driving. Even when connected to a 1A car charger, the battery drains faster than the charger can keep up with. Seems like iPhone 3G has some serious battery drain when in 3G data mode.
I am a little confused. My Verizon phone was able to roam on GSM because they used TDMA. Tell it was shutdown. The phone recognizes it as Analog. If PCS has TDMA, It could be technically be used on GSM.

I suppose you mean 500 mA. According to the USB 2.0 spec, that is correct. Notebooks and other low-power USB controllers may be limited to the 0.5 A as per spec, but many hubs can supply more current, and AC-adapters and DC-adapters that are specifically designed as charging devices (and are not otherwise USB compliant) can definitely deliver more than 0.5 A of current. 1 A is pretty standard. The AC-charger that ships with the original iPhone is rated for 1 A, and my car charger is rated for 1 A as well. Not sure about the new AC-charger that ships with iPhone 3G, but I would assume they kept the 1 A rating there as well.
My iPhone 3G wall charger says 1A on it. The Griffin USB wall charger I also have is also 1A. Same with my Jawbone's USB wall charger (1A.)
It definitely charges faster on the wall than USB on a computer by my observations.
