Where i can visit in Kunming since I will stay only 2 days? Where is the electronic/mobile market?

You cannot miss the Stone Forest (Shilin). Take a direct tourist bus from the East Bus Station to the Shilin directly or take a train to Shilin station first and then transfer to a shuttle bus to arrive at the scenic area. Apart from that, the Dianchi Lake and World Horticultural Expo Garden in the city are also worth your visit. For the rest time, you can go to the Yi Er Yi Street for the electronics and mobiles and go to Nanping Street for shopping and dining.
