Boy Genius has a source that informed him both the CDMA/Verizon iPhone 4 (code named N92AP) and iPad 2 may be heading into field verification testing:
Way down deep within iOS 4 is a pretty intriguing block of code. Our source says that the code queries the device, and if the device is either a CDMA iPhone or iPad 2, the device will auto-activate, thus bypassing the need for iTunes. We’re told this block of code has appeared every year consecutively before a major iPhone / device release, removed right before launch. This allows the products to be field tested by carriers (or partners) without having to activate the handsets or devices.
BG also says the upcoming iPod touch 4 is code-named N81AP. We should see that this fall at Apple's annual special music event for iPod/iTunes. iPad 2 should be announced early next year, and rumor has it the CDMA/Verizon iPhone might hit during the same period.
Anyone starting to believe that yet?
