Changes

Before the smartphones we know today were staples of mainstream culture, mobile phones, and their technology were pretty rudimentary and often relied on apps made in Java seeing as the language was designed to be portable (though Windows Mobile and Symbian were also somewhat popular as proto-smartphone platforms of choice). This didn't keep games from being developed for these platforms. Casual simplistic games and rip-offs of retro franchises thrived, but it attracted some genuinely fun games that forever remained obscure, such as those from Gameloft.

A free cross-platform language capable of working in devices with highly reduced capabilities. It was basically Java stripped down to the bare essentials.

While originally not intended for games (until its more advanced game-oriented API came), it became the ''de facto'' market standard for cell phone gaming - due in no small part to the SDK being free and without licensing costs.

==Japanese cellphones==

It is possible to develop applications that work both under ezplus, J-SKY and standard J2ME devices by using only MIDP1.0 APIs

Japanese mobile manufacturer NTT DoCoMo released [https://en.wikipedia.org/wiki/DoJa DoJa] (DoCoMo's Java) as part of their i-mode set of standards for mobile telephony. It is based on Java ME CLDC, but not MIDP. The profile received several updates, being later renamed to "Star". It was used on DoCoMo's mova and FOMA series of mobile phones, being first featured on the mova 503i from 2001.

DeNa (Mobage), Namco (Tales of Mobile) and Level-5 (RoiD) set up Steam-like game distribution portals specific to some cell-phone models yet i-mode based. The different names are to confuse dirty gaijin, probably.

===J-SKY===

J-PHONE had been purchased by Vodafone on 2001, which two years later took over the original branding renaming the carrier to Vodafone KK. The J-SKY technology became then known as "Vodafone Live!" and it was extended with the VSCL set of APIs.

On 2006, Vodafone KK was purchased by SoftBank Group, getting this technology rebranded again as "Yahoo! Keitai".
