PDANet is pretty weak speed wise imo and you have to pay more for PDANet than the 20 dollar hotspot plan if you want to use all of their services like https sites.. The Bluetooth transfer for PDANet, according to their forums, is like 300-600k per second, which is garbage. I get 20-35MB/s download using WiFi tether on my Droid currently.
I'm sure you will have to pay for it. I use WiFi tether on a rooted Droid...I'm in southern AZ if you can't see where I am located. I would only pay for the 3G hotspot until I can root it. I wouldn't ever use PDANet if you paid ME. I'm sorry but I've seen people using PDANet and Bluetooth is just too slow to pay a penny for, one time or otherwise.
I don't understand what you're asking....the phone is shipping with a WiFi tether app built in...why would you need PDANet at all anymore? You mean to make it free?
No I have an upcoming trip to Germany which complicates my order for the Droid X though because it officially comes out July 15th, which 12am 15th is 9am where I'm at and I'll be busy until lunchtime. Of course at lunch it will only be 3am in the States...
I have no idea to speculate about your PDANet question. I have never even considered PDANet for 1/10th of a second so I don't want to lead you astray on some random prediction.
I do find it hard to believe, and rightfully so, that Verizon would allow a company to basically steal all of it's extra WiFi hotspot revenue for 18 bucks.
