I have tried it and its still didnt work. I have a bug filed for like every internet aware 3rd party app I use because they all dont work with the system wide proxy settings you add to your wifi profile. I feel the pain so i know exactly what am talking about. 100% of 3rd party apps on maemo dont have proxy support. It has been a problem with the N810 but things just nose dived with N900. If you are behind a network proxy like your main connection is through a proxy (like many university students and cooperate workers) Just forget the N900 infact only the web browser and skype works.. no other core app works. no Internet radio, no gtalk, even though application manager works you need to use your proxy IP address instead of the hostname other wise the nokia repo wont load... Has if that is not enough.. you wont be able to use gpodder,mauku,qik,OMWeather,all the cool conversation pluggin, wikitunes .. i mean just think of any application that requires internet to work.. there would fail on the N900 if you are behind a proxy. and yeah I have filed a bug against almost everyone of them.. so am not just sitting down groaning
