Tutorial :Distinguish iPhone 3G from iPhone 3GS



Question:

Is it possible to distinguish an iPhone 3G from an iPhone 3G S using any of the properties of [UIDevice currentDevice]?


Solution:1

The best way to check is to use sysctlbyname("hw.machine", ...) as per How to tell if your code is running on an iPhone or an iPhone3G?

The returned result for 3GS should be "iPhone2,1"


Solution:2

I don't believe so - nor even 1G phones from 3G. You have to use sysctls to get more detailed model info.

E.g. see here


Solution:3

maybe simpler solution - try

[[[UIDevice] currentDevice] isMultitaskingSupported];  

iPhone 3G has no multitasking, while 3GS and newer have.
