The handset – codenamed Honami – was revealed by Sony Korea’s chief executive Kenji Sakai yesterday.
It is currently unclear if the phone will be launched in the UK. Kenji was reportedly only speaking about the device in relation to his home market.
The phone is expected to be officially unveiled by Sony at its IFA conference in Berlin this September.
Taiwanese website ePrice claims to have been leaked the specifications of the phone.
According to the site, the Xperia i1 will feature a 20.7-megapixel camera with a 1/2.3-inch image sensor. That is the same sensor size as is used in the Samsung Galaxy S4.
That is also smaller than the 1/1.5-inch image sensor in the recently announced Nokia Lumia 1020.
It also reports that the phone has a 5-inch 1080p display, is powered by a Snapdragon 800 quad-core processor, has 2GB of RAM and 16GB of storage. The handset is also said to come with a 3,000mAh battery and a 2-megapixel forward facing camera.
There is no way to verify the authenticity of the specifications as Sony does not comment on unannounced hardware.
The site also claimed that the phone will be unveiled officially between September 6th and 11th.
IFA 2013 is due to run between September 6th and 11th, suggesting that the phone will be unveiled at the event.
