I recently bought a Huawei phone from a large mobile phone dealer. £70 contract-free, with a dual-core processor and Android 4.1. Is there something I should be concerned about with this thing? It is remarkably cheap and seems good quality so far. I'll probably put Cyanogenmod on it if they come out with it, though.
