How to determine whether user is on Edge or 3G on iPhone

Question

Though it is relatively straightforward to determine if an iPhone is on Wifi or a data network programmatically in your application, I can\'t figure out a way to determine i

Answer 1

one way you can detect iPhone 2G for sure is to look at the device name as reported by the OS

#import 
+ (NSString *)deviceType {
    struct utsname u;
    uname(&u);
    NSString *returnValue = [NSString stringWithFormat:@"%s", u.machine];

    return returnValue;
}

the return value you are looking for is "iPhone1,1" to indicated iPhone 2G. combine this with the Reachability project to tell when they're on a cell network and you you have 1 avenue to guarantee that they are on an edge connection
