My friend cant find PTT option in his N95..he searched every folder and sub folder..though there is help text in Tools folders about it..but no icon anywhere in my phone..any N95 user ?

Some networks disable this application. If your that keen on using it then i suggest you change your product code with nemesis phone tools. Once complete do a nokia software update. You can find your product code via google.
The code you are looking for is EURO 1. Once you have completed firmware update have a look in the menu. Haypresstto PTT......

Go to Menu/Tools/Connectivity/PTT

Hope this helps

U cant use it if your network provider support it.
