Is the external antenna connector just for GSM, EDGE and the like, or can it be used for other stuff like WiFi and/or GPS antennas also?

on the top of my head i'd say yes
because it would be odd to put more then 1 antenna inside the device
when various parts could just demodulate the signals they needed from the
same antenna

The external connector is only for GSM and all data bands, GPS is a other antanna its quit different than GSM or WIFI bluetooth, wifi and bluetooth are the same (both 2,4 Ghz) that's also the problem when using them at the same time.
That's my vision.

are you talking about the antenna or the system to demodulise the signal ?
all an antenna is a dipol device which acording to the nyquist frequency http://en.wikipedia.org/wiki/Nyquist_frequency rules have to be min ½ of the wavelenght of the signal it's to recieve
as it's basicly just a conducting rod it would be silly to fit more inside the case then one would need

Hi

That's tru and that's whet I ment ,you coud not use the same conector for different frequenties (only to receive,not the GPS)the GSM and WIFI/bluetooth antenna have no inpedance, GPS I don't know it's a 3d antenna that's all i know, so it coud not tell the differece.
And why woud the do that WIFI/Bluetooth were made for 10 meter radius and it works.
and the GPS is extra it was not ment for the market.
