title: Emulate a slow iPhone
body: <p>I have an iPhone app (Objective C++). My beta testers - some of them, not all of them - are complaining of slow startup, 7 to 10 seconds. On my device (it's a 3GS), it loads in about 2 sec. On the device simulator - even faster. As things stand now, I cannot even isolate the bottleneck.</p>
  
  <p>Can I somehow slow down the simulator or a fast device? Setting the simulated hardware version to 2.0 does not help.</p>
  
  <p>As a last resort, I could try and borrow an old, slow device from a friend for a night or two. But I'd rather not...</p>
