title: Cannot use FTP to transfer files on iPhone 4 over 3G
body: <p>I have been using FTP on an iPhone 3GS in my app for almost a year with no problems. On my new iPhone 4 FTP fails all the time when using the 3G network. I have tried on 4 other iPhone 4's with the same result. I have tried multiple FTP servers with the same result. </p>
  
  <p>Steps to Reproduce: <br>
  1) Turn off wifi on iPhone 4.<br>
  2) Build and install code example SimpleFTPSample.<br>
  3) "Put" the lower right image (the larger the better. you may need to retry a few times to see the error)<br></p>
  
  <p>You will see "Network write error". I added some debugging code to print out the actual error and this is what I got. </p>
  
  <p>An error occured during FTP transfer<br>
  Description       : The operation couldn’t be completed. Cannot allocate memory<br>
  Failure Reason    : Cannot allocate memory<br>
  Recover Suggestion: (null)<br>
  Error Domain      : NSPOSIXErrorDomain<br>
  Error Code        : 12<br></p>
  
  <p>Any ideas for working around this?</p>
