Default Caring for the Elderly: iOS 4.1 Speed Boost on the iPhone 3G

Letís 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. Itís 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'm going to be painfully honest though. If you’re the kind of person that even remotely cares about how fast your device is or applications launch, you shouldn’t be using an iPhone 3G anymore.
however, if you're the kind of person who doesn't spend €500+ on a phone... 3G will do just fine

Unless you absolutely don't care about speed and fancy-ness and then you end up with an iPaq 614c

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
