has a calculator program that I use a lot it figures SQFT to Yards to Cubic yards etc.
I also like I Heart Radio I use it all the time to listen to radio at work.

If it is an ATT phone you will want to turn off Location Services
Goto Settings
Select Location Services
Scrol to the bottom
Select System Services
Turn OFF Diagnostics & Usage
Turn OFF Location Based iAds

This will stop ATT from sending you ads based on were you are at.

I am not sure if Verizon has this feature but if it does I would turn it off also.

have fun with it.
