Most iPhone users know the dreaded green bubble problem. For a while, when talking with friends and family in a group chat of iPhone users, the experience was very different. In short, Android users have always been able to join chats with iPhone users, but as soon as they did, the chat was downgraded to MMS versus iMessage. Android users can finally edit their text messages sent to iPhones, but they show up funny after. Of course, on iPhone, group chats including non-iMessage participants will still look like MMS or regular text chats.
