I had the same problems last week. After trying all proposed solutions with no success, it occurred to me that we had SElinux enabled on the server. In my case, and maybe for many other people, SElinux was responsible of the error message:
Unable to create directory wp-content/uploads/2013/04. Is its parent directory writable by the server?
My solution is based on the one proposed here: http://doc-ok.org/?tag=selinux which could be more suitable to other people's needs.
In my case, my wordpress directory resides in my home folder on the server, to which I have ssh access. Otherwise you will have to ask your administrator.
Anyway, this is my solution.
chgrp -R apache wordpress #change wordpress with your base directory for wp..
#alternatively, chown the whole directory to apache
chmod -R 774 wordpress/wp-content #if chown by apache, the permissions can be more restrictive
In my case not only the folder ownership / group ownership had to be changed to apache. Also the SElinux label of wp-content directory had to be changed to either httpd_sys_rw_content_t or httpd_sys_content_t:
chcon -Rv --type=httpd_sys_content_t wordpress/wp-content
This did the trick for me.
More information on SElinux can be found for example at:

and

chmod
with the-R
option to make it recursive? if not, you may have only changed/wp-content/uploads
and not/wp-content/uploads/2012
– doublesharpls -la
on the/wp-content/uploads
directory, what is the owner and permissions set to? Do you know what user Apache runs as? – doublesharp
