Hello. Bruno here.
I've been an iPhone 4S user for 2 years. And want to try something new. I ordered a new phone ( never-heard brand, 8-core less than US$ 150) from China, and found something wrong.
I googled for help and this forum just popped out. So I just turn here and see if i could get any help here.
But, still want to say hello to you guys first.
