GPRS (General Packet Radio Service) Question:

NTT DoCoMos i-mode is a mobile internet (as opposed to wireless internet) service popular in Japan. Unlike Wireless Application Protocol or WAP, i-mode encompasses a wider variety of internet standards, including web access, email and the packet switched network that delivers the data. i-mode users have access to various services such as email, sports results, weather forecast, games, financial services and ticket booking. Content is provided by specialized services, typically from the mobile carrier, which allows them to have tighter control over billing.
