I have an Iphone 4. How do I update the apps I have on it?

[iMore Question]

I have an Iphone 4. I would like to update the apps, including optionsXpress, on my phone. I don't remember how to do that.

AppStore app on the phone, or via iTunes on computer...update there and sync to the phone.

If you download the apps, they should be updated already.
