I have spent way too much time (over an hour) on what I though would be a two minute task. On the iPhone:
NSString * dateString = @"2010-09-11T00:00:00+01:00";
NSDateFormatter * formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"YYYY-MM-dd'T'HH:mm:ssTZD"];
NSDate *date = [formatter dateFromString:dateString];
RESULT: date == nil
What am I missing!! (Besides my deadline)

TZD isn't a defined formatter per the unicode spec. The document you've linked to elsewhere was a suggestion someone made to W3C, for discussion only. The unicode standard followed by Apple is a finished standard, from a different body.
The closest thing to what you want would be ZZZ (ie, @"YYYY-MM-dd'T'HH:mm:ssZZZ"), but that doesn't have a colon in the middle. So you'd need to use the string:
2010-09-11T00:00:00+0100
Rather than the one you currently have that ends in +01:00.
E.g. the following:
NSString * dateString = @"2010-09-11T00:00:00+0100";
NSDateFormatter * formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"YYYY-MM-dd'T'HH:mm:ssZZZ"];
NSDate *date = [formatter dateFromString:dateString];
NSLog(@"%@", date);
Logs a valid date object, of 2010-09-10 23:00:00 GMT.
Tip: try using your formatter to convert from an NSDate object to a string, then see what you get. It's often easier to debug in that direction than the other.
Have you read this?
http://unicode.org/reports/tr35/tr35-6.html#Date_Format_Patterns
That TZD at the end of your format string looks a bit dodgy.
I solved this issue using this code.
