NEW YORK ( TheStreet) -- Apple ( AAPL) is one of the few tech companies that repeatedly pushes the envelope with its hardware and software. The tech titan's reportedly testing the next iPhone, but will consumers clamor for it like previous versions? The Next Web reports that developers have started to see logs with an 'iPhone6,1' identifier, using iOS 7, which could be Apple's next mobile operating system. Apple has traditionally announced the next version of its OS at its Worldwide Developers' Conference in San Francisco during the summer, with the next iPhone coming shortly after, but given the recent market sentiment towards anything Apple, demand could be tepid. Sentiment has changed towards Apple, especially at the end of 2012, as the company released a slew of new products, including the iPhone 5, iPad mini, fourth-gen iPad, and a host of new Mac computers. I was impressed with the new Macs and the iPad mini, but the iPhone 5 offers incremental changes to the iPhone 4S, at best. It wasn't a drastic change, save for a slightly larger screen, thinner design and a new operating system. The markets reflected that shifting sentiment, particularly after Apple's last earnings report. In the final three months of the year, Apple fell 19.29%, compared to a decline of just over 3% for the NASDAQ. That's a massive change for the world's largest tech company, and something that won't be easily altered by a slightly thinner screen or an enhanced version of Siri. Apple bulls will claim that the hardware has already been perfected, and Apple is just tweaking it. That may be true, but consumers are always dazzled by the latest and greatest gadgets, which Apple has done so often in the past. There's a reason why the iPad, which revolutionized the tablet market, outsells offerings by Amazon ( AMZN), Google ( GOOG), and Microsoft ( MSFT). It's a relatively new product, whereas the iPhone has been around for half a decade, and has largely dominated mindshare. Topeka Capital Markets analyst Brian White believes Apple could move away from the traditional black and white iPhone color schemes, and also offer different sizes. "Our checks are pointing to more choices on the way with the next iPhone with expanded color options and screen sizes," he wrote, in a note. "By providing customers with greater choices with the same high quality performance of the iPhone, we believe Apple has the potential to further expand its market share in the rapidly expanding smartphone world." I'm highly skeptical Apple would have multiple sized phones, as the company likes to keep its SKUs relatively small, but adding to the color scheme (perhaps pink, green or red) might freshen it up a bit. Of course, this is just a cosmetic change, and not anything drastic.
