There have been a number of reports claiming that the next generation iPhone, currently being referred to either as the iPhone 4S or iPhone 5, will make its debut in September, several months later than the usual June/July releases of previous iPhones. Today the folks at 9to5Mac have added to the September launch chatter, reporting that the new iPhone is now in its final testing stage and that the device is currently slated to launch in September. This news comes to the site from "a previously accurate Apple source" who also claims that Apple and Verizon have yet to come to an agreement about allowing FaceTime use over 3G as well as over-the-air updates using Big Red's network.
It's also worth mentioning that 9to5Mac has found references to devices codenamed "N93" and "N94" buried inside the iOS 5 beta. There's not a lot known about either product, although the files do indicate that they're packing 5-megapixel cameras, which is lower than the 8-megapixel shooter that has been rumored to be appearing in the next iPhone. It's possible that these files have yet to be updated or that neither of these devices will ever actually make it to market. Another possibility is that the N93 or N94 could be handsets meant for use on Sprint or T-Mobile. A prototype iPhone running on T-Mobile's 3G network and sporting the N94 moniker leaked back in April, so that's something to consider.
Although nothing has been made official by Apple, it's looking increasingly likely that the new iPhone will indeed make its debut in September. There's still a lot that's up in the air when it comes to what kind of specs the new handset will pack, but one Verizon executive has let slip that the next generation iPhone will feature both CDMA and GSM radios. We're sure to hear more the iPhone 4S/5 as we inch closer to September, so stay tuned!
