Korean region G3 (F400) has 3 GB ram, and Korean G3 comes with a spare battery too (don't know if shop keepers here give two batteries or not). It has futher 3 variants F400S/K/L. It has lots of bloatware pre installed. They are cheaper than international variants, yet same quality. Google these F400S/K/L.
The other variant is international (D855) with 2GB ram and single battery. The specs you showed are of D855. D855 runs 3G and 4G in Pakistan, but i cannot confirm 4G compatibility of Korean variant.
