I have just got my second unit of iphone4 (16GB) yesterday from MC The Garden. I registered my name with the customer representative when signing up/purchasing my first unit couple of week ago and received a call on Saturday about the availability.

Not many people at The Garden, compared with weeks ago. I didn't have to wait long...got it within half-hour. Seen a few other people collecting theirs there too. I believe there are plenty of stock now.
