If the rumors are true and the next-generation iPhone will be unveiled at a September 10 event — invites are yet to be sent out — it will definitely run iOS 7. Apple has been sending out beta versions after beta versions so we can take this for granted.
We also know that iOS 7 will be available for previous models. However, we don’t think Apple will release iOS 7 to the public on the event day (even though it’s not impossible). On to the report: Nuance voice recognition software maker has sent out an e-mail stating that “iOS 7 GA will be released on September 10th”. As TNW notes, Nuance is not likely to have inside Apple information. There’s also speculation about GA being GM (Gold Master, instead of believed “General Availability”), which is basically as close to the public release as it can get.
Apple usually makes hardware available the next Friday after the event, which, might be September 13, or 20 (in case the September 10 event still stands). Making iOS 7 available for previous phone models would make owners happy, but would be a bold move impacting sales of the very phone that was supposed to introduce it.
Looking back to the iPhone 5, the one which shipped with iOS 6, it was introduced on September 12, with iOS 6 being available to previous phones on September 19, one week after the event
