I just got my iPhone 4 on Thursday and I am loving everything about it! I have had 3 Backberries previously. I love being able to click on a link that someone sends to me and not have it go to some mobile version of the site without showing me the article. I love having all of my music, apps and pictures synched with my iTunes and iMac. My work started allowing iPhones and Droids to connect up about 6 months ago and at least 50% of us are switching. I did not have a choice before. My work pays for my data plan so for now I am keeping my $30 unlimited.
I just sold my Bold 9000 on EBay for $175 with the charging pod. Not a bad deal!
