Three months of labouring has finally seen light. Apple has approved my first iPhone app and is now listed under 'Business' section of iTunes App Store worldwide. It's called "Korean Power Grid Info" - more info on WDSoft.com or App Store. Folks who want to see how much Korea as a whole spends electricity in real-time should find this app useful.
FYI, the app is released under Korean Power Exchange instead of my name or WDSoft.com because it represents the app best. All relevant data and information comes from there.
