I have recently purchased Nokia x7, I have update my phone to nokia belle. I was previously using skype verison 2.1.023 but I am not able to put my username and password on skype. I have noticed there is new version of skype for mobile phone that is 2.4.5, I am not able to download it from nokia official website. I am also using whats app but I can increase the volume of my whatsapp. Can you please help me what is the exact problem I am not able to understand and nor able to fix it.
