iOS Checking which iPhone they are running

[Kingbombs]

I know there is a way but having throuble with search results but i want to see if the user is running a 3GS or if they are running the versions before?

bassicly something like
if (version == 3GS)
//do something
else
//code for earlier versions

I know there are a few ways to do it, so please just put all the ones you know! Thanks!

Check the documentation for the UIDevice class. This should have everything you need. [UIDevice currentDevice].whateverProperty;

The class below is a category that will return the hardware model of the device, such as iPhone2,1 , iPod2,1 , Simulator return i386 ... I use this to tell the difference between different models of devices. There are also others ways such as check if the manometer is available if it is its and ipad or 3gs. Ect. but this is scalable to new devices.
