Let’s talk briefly about what makes the iPhone 3G (and 2G) fundamentally different from the 3GS. The iPhone 3G, like the 2G, is based around a 412 MHz ARM11 family Samsung SoC which implements the ARMv6 instruction set. It’s got 128 MB of LPDDR1. By contrast, the iPhone 3GS uses a 600 MHz ARM Cortex-A8 family SoC which runs the ARMv7 instruction set, and packs 256 MB of LPDDR1. The iPhone 4 similarly runs ARMv7 code.

By nature of the two platforms running different instruction sets, their underlying iOS kernels are completely different

I upgraded to iOS4 on my 3G right before I upgraded.. The phone had never lagged so much.. I also had it Jailbroken so that it also had the background image and multitasking enabled, and that only made it that much worse.. I did notice that my FreeMem app used to be able to free up about 20mb of memory, but after the iOS4 update it would never free more than 5mb. I gave it to my friends son as a bday present, I'll have him try this and see how much better it really is..

what? that phrase doesn't make much sense

duh, there's a reason those items are disabled, background image requires beefier GPU, multitasking requires more memory

if you leave background & multitasking disabled, also disable the spotlight search, the device seems to be quite snappy; from the benches by Anandtech, as snappy as 3.x in most cases
