If I take a pic with my phone I send it to my home Email. Then save it to my pics folder for future use. Can't help nor have a clue how to post pics directly with your Iphone.
I don't have time during the day to get online with a phone so just have a basic camera phone to talk on. Besides that the screen is too small. I like my 17" monitor and one of these days I'll figure out how to hook a laptop to the 42" HDTV to get on TBN.
I do carry 2 cell phones, one issued by my work, the other is my personal phone. (I don't like to use the work phone for personal calls).
I used to take phone pics of strange things I saw while driving but can't do that anymore. It's against the law here in NY. Big fine and now 2 points on your license if you are caught talking not using a hands free device or texting while driving.
