Skype released the beta version of Skype 2.2, a software client that allows Windows Mobile smart
phones to access the company’s voice over Internet Protocol (VOiP) service over Wi-Fi connections. Previous versions of the software were compatible only with Windows Pocket PC devices. The beta works on 120 different Windows Mobile devices, Skype said. Users in range of a free Wi-Fi network can make free VOIP calls to other Skype customers. Users can also pay via their SkypeIn and SkypeOut accounts to receive and make calls to landline phones.
New features in Skype 2.2 for Windows Mobile include an enhanced screen with presence status and notification of events such as missed calls and voicemails. The client also now supports secure connections including HTTPS, HTTPS/SSL and SOCKS5 proxies.
Skype recently said that it has seen 5 million downloads of Skype for Pocket PC. PC World - Skype Supports Smart Phones
