Lenovo Does The Dual SIM Jig At CES 2013
As for the IdeaPhone S720, this will be a smaller sibling with a 4.5″ IPS LCD screen of qHD resolution (245ppi), powered by Android 4.0 Ice Cream Sandwich and a dual-core MTK processor. At the back, you will find an 8-megapixel shooter, while the front has a 1-megapixel camera.
For those who are on a tight budget, the two entry-level A series smartphones would be the IdeaPhone A800 and A690, with the latter running on Android 2.3 Gingerbread and a single-core 1GHz processor, truly making it obsolete even before it rolls off the assembly line in this day and age.
