Very easy: open a proXPN account (free) and follow the instructions on their support site on how to set up your iPhone. This will hide your real IP.

I think @AI Everett is 100% correct. The only suggestion I would make in addition to his is this:

• Copy your existing profile picture (if you really like it and want to keep it, else upload a new profile picture; it is your choice). Leave this image in the album called "Scrapbook photos".

• Move your existing profile picture, which will include your friends' comments (I'm guessing you want to keep them), from Scrapbook photos to a different album. You can use an existing, private album, or create a new album that is accessible only to certain people or circles.

• Use the new version of the picture in your Scrapbook photos as your profile picture. Make sure to disable comments on in it!
