Some might argue it's the most subtle update in the iPhone family thus far, but Apple's iPhone 3GS still seems to be moving the sales meter, regardless. The latest and greatest iPhone officially hit the market a few weeks back, and even though Apple claims that demand is still far outpacing supply, we're of the belief that most everyone who wanted one has managed to snag one by now. During our time with the unit, we definitely didn't find too many reasons to upgrade from the already solid iPhone 3G, but given that you probably did anyway, we're eager to hear how things have turned out. Did you upgrade from a prior iPhone to this? Are you joining the iPhone family for the first time? What gripes have you found impossible to ignore? Are you still up in arms about AT&T's inability to provide MMS / tethering service? Are you, like us, completely roiled by the unit's lack of multitasking abilities? Go ahead and let it rip in comments below -- we're guessing Apple has about 11 months or so to take your opinions to heart.
