iphone and ps3 problems

Alright so I recently upgraded to the airport extreme got it all hooked up and have my macbook and a hp laptop both connected to it wirelessly no problem. The thing is my iphone doesn't see the wifi network and neither does my ps3. The laptop seen it fine so its not hidden, also I have an airport express that I could possibly run the ps3 through if that will help. Thanks

nevermind figured it out it needs to be out putting in 802.11g as well for them to connect if anyone else has that problem
