On Monday, we’ve just shown you some leaked pictures, but we can now confirm the “world’s thinnest smartphone”, NEC Casio Mobile’s MEDIAS N-04C, is real. And provider NTT Docomo, Japan’s biggest mobile carrier, doesn’t want to lose time in bringing it to market: it will hit stores over here as early as March 15.

As reported, the Medias measures just 7.7mm, which makes it the slimmest 3G smartphone out there (the Galaxy S II is 8.49mm thick).

At 105g, it’s pretty light, too (the iPhone 4 weighs 137g), especially when you consider what the device packs:

• 4-inch LCD touchscreen with 480 x 854 resolution
• Gorilla Glass
• Android 2.2 (2.3 update in summer this year)
• 5.1MP CMOS camera
• i-mode compatibilty
• 1Seg digital TV tuner
• e-wallet function
• 3G/GSM roaming
• microSDHC card slot
• GPS
• Bluetooth Version 2.1+ EDR
• Wi-Fi
• HSUPA
• infrared communication

Docomo plans to offer the Media in black and white. No word yet from NEC Casio Mobile if this beauty will be available outside Japan, too, at some point.

Update:
Here is a good video shot at Docomo’s press conference today:
