Samsung SLM SGH-A747
Not a Replacement for the A717
That's exactly why we write the little text intro to each spec sheet that we do... so you can tell the bull from the crap.
Samsung can say whatever they want, but a horse is a horse.
The A747 and A717 are almost exactly the same phone except for screen specs. If the A747 is part of "its own line", that's strictly in terms of marketing, not reality.
