Well, at least let's hope someone will manage to come up with a "iPhone dock to iPhone 3G dock converter," so those audio systems I mentioned above won't instantly become obsolete as soon as their owners will upgrade to the iPhone 3G, but this is not all - now, let's see what else can be bad about the iPhone 3G!
Another possible issue with the iPhone 3G is long term cost. To make a longer story short, during the first two years, you'll have to pay $160 more because the pricier data plan for the iPhone 3G, compared to the old iPhone.
The iPhone 3G's camera still doesn't have a flash, and there are no replaceable batteries for it, either.
This should be everything I can think of now...but there's also Samsung Instinct, a very interesting "potential problem" (of) for the iPhone! What do you think? Any other issues with the 3G iPhone you can point out? Please, go ahead and let us know!
