HTC's (High Tech Computer Corp.) CEO Peter Chou and Vodafone KK President and Representative Executive Officer Masayoshi Son today signed a strategic collaboration agreement under which both parties will collaborate to develop and sell 3G PDA Phones in Japan.
With this partnership, HTC, the world's leading provider of Microsoft Windows Mobile devices, will utilize its global experience to expand both companies' customer base and market share in Japan. By selling highly advanced 3G PDA Phones manufactured by HTC, Vodafone will gain a stronger foothold in the Japanese market.

It wasn't announced today which device(es) both parties plan to launch first but it's most likely, that it might be the HTC Hermes/HTC TyTN which HTC announced before to sell via NTT DoCoMo as hTc Z
