Dropping iPhone 3GS Support for new app

Question

Is it possible to drop the support of iPhone 3GS for new App? Because I'm doing porting from iPad game to iPhone. The 480*320 resolution is too small. Its very hard to port my current game on it.. but iPhone4/4s with high resolution works fine!

Thanks

Take a look at UIRequiredDeviceCapabilities you can specify inside Info.plist.

There is no direct way to limit "device-support" to the iPhone 4(S) / iPad (2), but you can ask for front-facing-camera because that's only included in the iPhone-4-familiy :) On the other hand you'll also drop support for the original iPad if you use this way …

I'm not quite sure that you can do it from a build level. But you can do it from code level by detecting the device version like this (Not the best way of doing it),

- (NSString *) platformString{
    NSString *platform = [self platform];
    if ([platform isEqualToString:@"iPhone1,1"])    return @"iPhone 1G";
    if ([platform isEqualToString:@"iPhone1,2"])    return @"iPhone 3G";
    if ([platform isEqualToString:@"iPhone2,1"])    return @"iPhone 3GS";
    if ([platform isEqualToString:@"iPhone3,1"])    return @"iPhone 4";
    if ([platform isEqualToString:@"iPhone3,3"])    return @"Verizon iPhone 4";
    if ([platform isEqualToString:@"iPhone4,1"])    return @"iPhone 4S";
    if ([platform isEqualToString:@"iPod1,1"])      return @"iPod Touch 1G";
    if ([platform isEqualToString:@"iPod2,1"])      return @"iPod Touch 2G";
    if ([platform isEqualToString:@"iPod3,1"])      return @"iPod Touch 3G";
    if ([platform isEqualToString:@"iPod4,1"])      return @"iPod Touch 4G";
    if ([platform isEqualToString:@"iPad1,1"])      return @"iPad";
    if ([platform isEqualToString:@"iPad2,1"])      return @"iPad 2 (WiFi)";
    if ([platform isEqualToString:@"iPad2,2"])      return @"iPad 2 (GSM)";
    if ([platform isEqualToString:@"iPad2,3"])      return @"iPad 2 (CDMA)";
    if ([platform isEqualToString:@"i386"])         return @"Simulator";
    if ([platform isEqualToString:@"x86_64"])       return @"Simulator";
    return platform;
}

Hope this will help you to a certain extent.

I don't think it's possible as I took a look in this great reference chart http://blog.manbolo.com/2012/10/30/uirequireddevicecapabilities-and-device-compatibility-matrix

The best closest is to required front-camera or gyroscope but it will cut out iPad 1 from your support devices. I think I have to admit and do my best to support iPhone 3GS, I just don't want users to download and experience something bad even if it's small portion of users are still using it.

Add Required device capabilities to your info.plist and the value camera-flash . This will limit the app to only run on devices with camera flash (eg iPhone 4/4S) or use front-facing-camera to include iPad 2 and latest gen iPod Touch.
