MacRumors reports that Apple is expected to hold a press conference in the first or second week of October — pushed back from the prior September speculation — to introduce its new iPhone, iPod Nano and iPod Touch devices.

But contrary to prior rumors, the latter non-telephony device won’t see a major overhaul according to reports. Instead, it will see the introduction of a white model. Only minimal changes are expected with the current 4th-generation hardware including an oleophobic coating for the display and a revised ambient light sensor.

As indicated earlier, white parts for the iPod Touch leaked into the supply chain back in July. These suggested that Apple plans to offer white models with no apparent changes to the overall design, and could even be applied to the existing fourth-generation model.

Prior rumors have claimed that Apple plans to introduce a 3G-capable iPod Touch, a cheap, cloud-based version of the iPhone 4 and the hardware refresh that’s supposedly the iPhone 5. Recent reports have also indicated that the iPhone 5 isn’t scheduled to appear at all, that Apple won’t be ready until next year, leaving the cheap iPhone 4 all alone in the spotlight next to its touchy comrade.

As always, Apple rumors should be taken with a grain of salt. There’s so much circulating the Internet that it’s hard to get a clear picture of what Apple has in store for consumers. And now that Steve Jobs has stepped down from his position, there’s no indication that the company will stick to its customary reveal and release dates. We’re still in September, so Apple has less than two weeks to stay on its iPod refresh schedule.
