I assume you really mean the 5800 which had a 434MHz processor, 128 MB of RAM, resistive touch screen and no GPU. I have used Android on a device with twice this spec and it was CHUFFING TORTURE. The 5800 was great budget device of course, full of functionality, but stop pretending this was ever an iPhone competitor. Again it is a testament to Symbian you can get acceptable performance from such extraordinarily modest hardware.
