Simulated Mobile Carriers selection list -- 5

I need a tool, preferably a plugin or a modification of the existing User-agent-switcher (the open source Firefox add-on/Chrome ext) that will expand this add-on options by giving the possibility to simulate various Mobile Carriers from EU countries and US, Canada, Australia, etc. The final result should be this: - whenever setting a country (from a 3rd party VPN/proxy) and the user-agent-switcher to simulate a mobile device, THIS TOOL should give the option to chose from multiple carriers listed by countries, and simulate them correctly. List of carriers that needs to be integrated: - Austria (Hutchison, Mobilkom, Orange, T-Mobile) - France (Bouygues, Orange, SFR) - Germany (E-plus, Mobilcom, O2, T-Mobile, Vodafone) - Italy (H3G, Tim, Vodafone, Wind) - Netherlands (KPN, T-Mobile, Tele2, Vodafone) - Norway (NetCom, Network Norway, Tele2, Telenor, Ventelo) - Spain (Movistar, Orange, Vodafone, Yoigo) - Switzerland (Orange, Sunrise, Swisscom) - UK (Hutchison, O2, Orange, T-mobile, Vodafone) - Argentina (Claro, Movistar, Personal) - Brazil (Claro, Oi, Tim, Vivo) - Mexico (Lusacell, Movistar, Telcel) - Turkey (Avea, Turkcell, Vodafone) - US, Canada, South Africa and Australia (at least 1 carrier from each) - possibility to extend/modify/adapt carrier list This tool should work as a Windows browser (Firefox15*/Chrome18*) add-on/extension OR as a WinXP* standalone application. * means "and above".
