Yahoo! Keitai, previously Vodafone Live! and J-Sky (Jスカイ) was a mobile internet service created by J-Phone before the company was purchased by Vodafone, then SoftBank. It offered a means to allow mobile phones to access the internet.
Sega began supporting the service in Japan in November 2000 with software releases by WOW Entertainment[1].
With the release of the J-SH07 in 22 June 2001, J2ME support was added, and a tie-in with United Game Artists and Space Channel 5 meant every phone was bundled with Tsuwa Shichouritsu.
Hardware
Unlike its main competitor, i-mode, the Yahoo! Keitai service did not have consistent naming schemes for its products, and much of the terminology would change as Vodafone, then SoftBank took over operations. Like many third-parties Sega chose to group handsets by the size of the J2ME applets (officially Java appli (Javaアプリ) then V-appli (Vアプリ) and finally S! appli (S!アプリ).
50KB
Starting with the J-SH07, J-Phones could run J2ME applets up to 50KB in size.
