I've always had problems with iPhone group messages, mainly because if someone is not online at any given time they tend to 'drop off' the conversation. It also means that those who don't have an iPhone can't join in.
WhatsApp messenger means that I can now group message loads of people, whether they have iPhone or not. Its so much quicker, and free as long as you have Wi-Fi. Its easy to use too - and it was free to download! A simple but very effective app.
