why dont you put all of your questions on one thread instead of opening 3 different ones?? anyway you dont need a router. just plug your iPhone into a usb port on your computer and turn on tethering and you have internet and can surf and talk at the same time.
I appreciate your effort but, I have learned that if you put too many variants of the same question in one topic, then it becomes more likely that you won't get all of your variants answered.
Also, as in this instance, some will not read the question. The reason I am asking about the router is, as stated in the question:
"Would like to do this because for my purposes I have both laptop an desktop running, but use them for different things.".
So, to repeat the question, "...can one connect it to a wireless router that has a USB port for an aircard, but instead of using an ATT aircard, use the iphone w/ a USB card ?", and I am hoping that someone will help me with information.
Also, the ability to receive calls while tethering is essential because I have some virtual phone numbers that I use in my advertising, and I have these call forward to my cell so that I can be the first to answer these cold calls, as I have found that my secretary is not the best a reeling in a potential customer.
I have one or two USB extensions around that I should be able to patch into the data cord from the phone. I always keep my laptop plugged into 110 at the office, so I don't expect any problem with battery power in the office. At remote residential locations, I typically have my laptop running about 3 hours, so, there too, I always plug the laptop into a wall outlet.
Again, I appreciate your help.
