Sham Sui Po is the place to go but as HKT says, you need to know your stuff.
Another option is to take a train up to Shenzhen - this is
the mobile phone capital of the world. There are numerous places but one that I recomend visiting:
4A-043B, 4/F
Hua Jiang North Rd.
Literally 4 floors with hundreds of counters of phones - all local Chinese, all reasonable quality and price.
