What network is your friend on? Sprint has a 160 character limit on sms messages. If you send or receive a text longer than that, it's split up into multiple parts.
Was it a long message? I just switched to AT&T from sprint and let me tell you, my wife sends long messages. They would come through in 7 or 8 parts sometimes and my phone would go crazy on notifications.
