Is there any android apps that have a camera app to where you can turn the lens around like an iphone camera?

Q. Hate taking pictures on Android phones you can't see how you come out.

A. Every Android device on Gingerbread (2.3) or higher, (90% of the market) supports front-facing cameras. Virtually all camera apps have a "Back/Front" button to toggle which camera to use.

So, yes.

Q. Hate taking pictures on Android phones you can't see how you come out.

A. My Android phone has a secondary camera that lets me see pictures that are taken (of my or someone else's face, based on assumption). Try looking in the settings of your camera before you take a picture.

How can I download apps to my pc from Android Market instead of downloading with an Android device?

Q. i want to download android apps to my pc from android market for my android device. any possibility? i don't want to download using my android device.

A. Well, if you want them on your phone, but not downloading via your phone, go to market.android.com and login and download.
If you want to run on your computer, that's a bit trickier. You have to download an Android sdk (software developer kit), run it, etc. But that's really hard.
Hope I helped!
