Since you want the request to happen synchronously, why not just use

+[NSURLConnection sendSynchronousRequest:returningResponse:error:]  ?

mainly because i want (need) the feedback callbacks, so i can get the anticipated size and progress of longer downloads.

Recursively pumping the run loop like that in the default mode is
discouraged.  I don't know the specifics of why, but crashes such as
you're seeing could be part of it.

do you have any references on this and what could/should be done internally? i saw that there are some runloop options (ie a mode) specifically for NS(URL)Connections as well, but it seems that one doesn't exist on the iPhone (contrary to docs), nor could i find any info on what this would do differenly...

thanx,
marc
