iPhone tethering didn't work with iPad because it required Bluetooth pairing. Is iPhone with iOS4.3 going to allow tethering to an iPad since it'll just be like any other WiFi hotspot?
Not in the sense that I mention. The carrier only enables tethering, not which devices can connect to it.
Once the WiFi Hotspot feature is enabled (with the carrier's permission) it becomes just like any other WiFi hotspot which even the iPad can use.
Currently, even if your carrier allows tethering, you still can't tether to an iPad because it must be via bluetooth or USB.
Now, unless the WiFi hotspot feature specifically picks out and blocks iPads as clients, then the iPad3G is just about to lose its raison d'être.
Well, that decides it, I'm getting an iPad 2 without 3G.
I was thinking of getting a 3G to future proof myself in case I started wanting to use the iPad outside of my home, but I also didn't have the stomach to pay for yet another data plan. I already pay for my home internet and iPhone data plans and a third one for the iPad was beginning to get crazy.
This makes the decision much easier. I already use my iPhone to tether to my MacBookPro.

if your in the US and on AT&T, it looks like your going to need a tether data plan on your iPhone, which is an additional $20 a month from your current data plan and a 2GB data cap (so like $45 a month for data). I read somewhere that Verizon is going to include it free with your data plan (so only $30 for unlimited data)
