Let's count, shall we?
Including the stationary apps at the bottom, I have a total of 52 apps, 32 of which aren't standard equipped.
The ones I use most are probably the flashlight, Where's Waldo?, MASH, Facebook, Twitter, Shazam, and Bank of America...along with MLIA, FML, and TFLN. Those are just the most used purchased/downloaded ones. Add to those the standard most frequently used such as: Voice Memos, Email, iPod, Safari, Text, and Camera and Photo Gallery. :)
My phone is quite handy.
