There's a lot of sites out there listing the original 145.825 frequency for the ISS APRS frequency, but if you look closely at the spot reports at http://www.issfanclub.com/packet-reports you'll quickly notice that it's operating on 437.550 UHF at the moment. As it says at http://www.ariss-eu.org/frequencies.htm

** The amateur radio station located in the Columbus module is currently operational with the UHF Ericsson transceiver and packet system using the frequency of 437.550 MHz.

And this was announced back on June 11, 2012 at http://www.issfanclub.com/node/34092
