I found temporary work around.. Set up a new contact in your Contacts on your iPhone, or iMAC. Do not use the group contact, just a regular individual contact card.
Type the name of the group into the Company space.
Enter all the e-mails into the one e-mail space.
The format you need looks like this:
Put the person's name in " " and the email in < >. Then separate each person with a comma.
"name one" <name1@mail.com>, "name two" <name2@mail.com>,
and you are done.
To send an e-mail to the group, just type the Group name into the To: field and your iPhone will think it is a company and fill in all the addresses. The key is to separate them with commas.
