Cannot use FTP to transfer files on iPhone 4 over 3G

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.

Steps to Reproduce:

1) Turn off wifi on iPhone 4.

2) Build and install code example SimpleFTPSample.

3) "Put" the lower right image (the larger the better. you may need to retry a few times to see the error)

You will see "Network write error". I added some debugging code to print out the actual error and this is what I got.

An error occured during FTP transfer

Description : The operation couldn’t be completed. Cannot allocate memory

Failure Reason : Cannot allocate m开发者_如何学Pythonemory

Recover Suggestion: (null)

Error Domain : NSPOSIXErrorDomain

Error Code : 12

Any ideas for working around this?

This ended up being a bug in apples code back when I posted this
