For all these new additions, though, there are still a few things left un-fixed in the iPhone 3G. One that receives an inordinate amount of attention is the lack MMS support. It's one of these issues you either care about or don't – personally I've never used MMS and don't plan to start – but for those see it as essential, it's a black mark against the iPhone.
Less forgivable, however, is the lack of support for the Stereo A2DP Bluetooth profile. This means that you can use ordinary hands-free headsets but not Bluetooth headphones, a logical and fairly straightforward next step. Given the obvious portability of the iPhone and its "connected everywhere" status it seems a bizarre omission.
Fans of camera phones will also be disappointed by the iPhone 3G, as it retains the relatively basic 2.0 Megapixal camera of the original. It lacks any kind of LED flash and though in natural light it's just about passable, as you can see from the shot on the right, it tends to produce blurry and noisy pictures in low light.
Having praised the interface earlier, there is at least one palpable problem. Though the virtual keyboard is in most respects superb, the iPhone is still very selective about when and where one can use the slightly larger landscape keyboard rather than the portrait one. This inflexibility is particularly galling when composing emails and text messages even if, as already pointed out, the overall experience is very good.
Happily, one area that has seen significant improvement is call quality and signal reliability. 3G obviously helps here, but even without it the iPhone 3G is a significant improvement on its predecessor. It doesn't drop calls randomly or lose signal for no apparent reason and 3G signal quality is generally good, even in variable coverage areas.
