If you still aren't tired of yet more iPhone rumors, here's a fairly juice one that's fueled by the crafty digital sleuthing of an AppleInsider reader. By dissecting the latest iPod firmware update, the reader found references to "t_feature_app_PHONE_APP" and variables such as "kPhoneSignalStrength", "prPhoneSettingsMenu" and more. To further fuel the fire, it's unlikely that this code has anything to do with the Motorola phones as they use an entirely different operating system. If you're interested in seeing the rest of the findings, including references to an iPod-based search application and an iPod keyboard, check out this AppleInsider forum thread.
Engadget is betting that we could see this now-infamous iPhone as soon as WWDC, beginning Monday August 7th, 2006. I guess time will only tell if Steve pulls an Apple-branded phone out of his jeans any time soon.
