ABGrouper: allows you to create groups like (family, girls, footy mates etc)
GroupSend: allows you to send to these groups, and also allows the ability to mark more than on recipent when you press the '+' button when creating a message (it puts a tick next to there name then you can click done once youve selected all the recipents you want) ive tried this with 50+ recipients and it works perfectly.
Note: If you have a contact with 2 numbers it will send it to the mobile contact or if there are two mobile contact it will send it to the upmost mobile contact.
