-is wifi generally considered faster than 3g? How much more?
-when using the iPhone on a wifi network does it use any data allowance?
-is it worth getting wifi at my house from my CPU to have a faster iPhone and less data usage from 3g? (considering dropping the unlimited data plan if so)

    802.11n equipment will generally report connections in the 130-150 Mbps rated range. 3G a minimum data rate of 2 Mbit/s for stationary or walking users, and 384 kbit/s in a moving vehicle, but various rates are sold as 3G by carriers so this will vary from carrier to carrier.

    -when using the iPhone on a wifi network does it use any data allowance?


    No.

    is it worth getting wifi at my house from my CPU to have a faster iPhone and less data usage from 3g? (considering dropping the unlimited data plan if so)


    Yes. Since iphone 4 supports N, make sure you set up an N speed router to take full advantage of the new phone.

    Your 3GS only supports up to G speed, the new phone will have a N speed chip(802.11b/g/n Wi-Fi (802.11n 2.4GHz only)).

    802.11n is the speed, 2.4GHz is the channel. There are are number of dual channel routers on the market(2.4GHz & 5GHz) capable of broadcasting on both channels simultaneously or a single channel router can be set up to broadcast on either channel.

    just spoke to an AT&T rep (this confirms AT&T website)...

    to use any iPhone, you must have both voice and data plan.

    You can't drop data plan and keep only voice plan.

    No. Only the iphone 4 will have an "N" chip. Software can't change hardware .
