Why does the iPhone fail to time stamp each sms message? For instance, I will receive a text message at 11:00 am - I will reply at 11:10 am and there is not an updated time stamp applied to my reply. I have phoned Verizon - this is an issue with the operating system. The representative suggested I look into downloading an app. I can't seem to find one that addresses this issue. Is it just me, or does anyone else appreciate knowing when a message was sent and received? Even the BlackBerry could do this!
