Can’t get enough of the iPhone 4G news after seeing the latest leaked pictures? While it’s not an official date for the iPhone 4G, AT&T has apparently been sending out Upgrade Eligibility notices to AT&T subscribers, notifying them of the upgrade date being switched from 11/21 to 6/21. If you’re wondering what this means, it could be a strong indication that the iPhone 4G will be announced by then, which is something that has been speculated about before. After all, if you announce a new iPhone, you’re obviously going to want existing users to upgrade as well, right? There are a few question marks, though, as June 21st is a Monday, while Apple’s iPhone has traditionally been launched on a Friday. Have you saved up enough pennies to get the latest iPhone 4G when it’s launched?
