According to the source, the flamboyant Windows Phone 8-powered smartphones from HTC, namely the Windows Phone 8X and 8S, are expected to cost around 500 euro ($645) and 300 euro ($390), respectively. A few reported carrier partners in Europe will include Vodafone , O2 and Telekom (T-Mobile). It’s important to note that HTC hasn’t confirmed the report. So a little dose of scepticism will definitely help. Meanwhile, stay tuned for Microsoft’s official event today where Windows Phone 8 will be further detailed.
