Know which number are you SMSing

The iPhone 3G has a unique way of displaying SMSes from your contact list. It's format is very similar to iChat. Tap on the SMS icon and you will see a list of names that you have SMSed before. Tap on the name and you will see the thread of messages you have sent before, like iChat.

The one problem I faced is that if a name has multiple mobile numbers attached to it, I will see the name appear multiple times in the SMS application. I will be clueless on which mobile number that name represents, and I will not know which number am I SMSing.

Not anymore. To know which number the name represents in the SMS application, just do the following:

1. Tap on the SMS application, and the name of the person you're interested in SMSing
2. Scroll to the top of the page or tap on the time at the top bar
   
3. Tap on Contact Info
4. The number highlighted in blue is the number that you're SMSing

That's it...
