Lost search function iPhone after upgrading to 4.3 Does anyone know how or why the search function in my text messaging is no longer working correctly after I upgraded to 4.3 on my 3G iPhone? 

All was fine until I upgraded and now even tho I can see a name in a text for example I search for it and it comes back as "No results".
Searching SMS messages was disabled due to battery life and performance concerns for the 3G, you can see this in the iPhone: Which iOS 4 software features does my iPhone support? article on apple.com

  iPhone 3G does not support Spotlight search for SMS/MMS messages.
