Hello , I install SDK 4.0 with xcode 3.2.3. When i built my application in simulator it works fine. But when i built it for device the following error comes. error: -fasm-blocks option not supported for ARM If i change Architecture - armv7 I got the following error.(My device is iPod Touch with os 3.x) Can't run 'Applicationname' - was built for 'armv7', but device requires 'armv6' or compatible architecture.
