Lol, I see you are one of those apple fan boy types, and it WASNT a dig at your precious apple though, was just in general about any technology product. so not going to argue the toss over it.
In fact I have a 3gs ive had for over 2 years, no major faults in that time, very happy with it. Am not anti-apple at all.
Fundamentally the longer any product has been out before you buy one, the more likely any software/firmware/hardware bugs have been ironed out.
So statistically the sooner you get it, the less likely it will be problem free.
