Skype runs on a number of platforms, and on October 29, 2007, Skype launched its own mobile phone under the brand name 3 Skypephone, which runs a BREW OS. Other platforms officially supported include:



    * Around 50 mobile phones, as of 2008

    * The Nokia N800, N810 and N900 Internet Tablets, which use the Maemo environment

    * Both the Sony mylo COM-1 and COM-2 models

    * The PlayStation Portable Slim and Lite series, though the user needs to purchase a specially-designed microphone peripheral. The PSP-3000 has a built in microphone which allows communication without the Skype peripheral. PSP Go has the ability to use Bluetooth connections with the Skype application, in addition to its built-in microphone.

    * Mobile devices running Windows Mobile; in February 2010, Skype announced its decision to discontinue development Skype for Windows Mobile.In May 2010, Skype announced it would not develop a version of Skype for Windows Phone 7.

    * Symbian; a limited beta was announced on December 10, 2009, and was available for several different Nokia phones

    * The X-Series together with mobile operator 3. However this uses a regular mobile phone call and iSkoot to a Skype gateway, rather than mobile Internet. Other companies produce dedicated Skype phones which connect via WiFi

    * iPhone OS, using an official application released on March 31, 2009. As of version 2.x, the iPhone application is capable of placing voice calls over 3G and EDGE networks. Skype announced it will charge a monthly fee for this feature at the start of 2011.

    * A variety of Verizon Wireless BlackBerry® and Android™ 3G Smartphones, through Verizon's Skype mobile™ service. Skype is ‘always on’, meaning customers can receive Skype calls, instant messages and see friends’ presence any time the phone is on. Skype usage isn't charged against customers’ monthly Verizon Wireless minute allowance when calling another Skype account (Skype-to-Skype). Customers in the US use minutes from their calling plan when calling US land lines or cell phones.



Recently a number of manufactures have launched hardware devices compatible with Skype. These are usually either tethered to a PC, or have a built-in Wi-Fi client to allow calling from Wi-Fi hotspots like the Netgear SPH101 Skype Wi-Fi Phone, the SMC WSKP100 Skype Wi-Fi Phone, the Belkin F1PP000GN-SK Wi-Fi Skype Phone, the Panasonic KX-WP1050 Wi-Fi Phone for Skype Executive Travel Set, the IPEVO So-20 Wi-Fi Phone for Skype and the Linksys CIT200 Wi-Fi Phone. There are also embedded cordless Skype phones based on DECT, which do not need a PC either, like the DUALphone 3088 from RTX. Netgear and SMC's Wi-Fi phones are considered the two major competitors in the market, with reviews of the Wi-Fi phones giving them equal coverage.



The Skype Wi-Fi Phone is a wireless mobile phone that allows users to make Skype calls, using a wireless Internet connection. The Skype Wi-Fi Phone has an on-screen menu that lets Skype users see who is online and available to talk, similar to what is seen on a PC. It can also be used to talk with non-Skype users. SkypeOut minutes can be used to call any phone for a low price and no monthly fee. The Skype Wi-Fi phone does not contain a web browser therefore can not access hotspots, which require web-based login or authentication.



Third party developers, such as Nimbuzz and Fring, have allowed Skype to run in parallel with several other competing VoIP/IM networks (Nimbuzz has even NimbuzzOut as competing paid service) in any Symbian or Java environment. Nimbuzz has made Skype available to BlackBerry users.
