After Steve Jobs died back in October, he had reportedly left Apple (Nasdaq: AAPL) with four years' worth of products in the pipeline. Even as the iPhone 4S was unveiled the day before his death, he supposedly oversaw the development of the next-generation iPhone that will follow in the iPhone 4S's footsteps.

Among other products that Jobs had envisioned was -- believe it or not -- an "iCar" to disrupt the automotive industry, according to recent comments from Apple director Mickey Drexler. Drexler said it was one of Jobs' dreams, but he never designed one. Another one is, of course, the Apple TV set to invade the living room, which Drexler effectively confirmed by referring to "the living room [Apple will be] dealing with at some point in the near future."

One of the last products that Jobs worked on that will actually soon seen the light of day is the next iPhone. Bloomberg reports that Jobs had "worked closely on the redesigned" iPhone before his death. Bloomberg is also chiming in and affirming that its sources point to a 4-inch display on the next model.

At this point, instead of looking at dubious rumor sources, we're now talking about The Wall Street Journal, Reuters, and now Bloomberg all separately corroborating the claims of a larger iPhone this year. These are reputable news sources that have more to lose from bogus reporting, unlike usual suspect Digitimes and its hit-or-miss ways.

Google (Nasdaq: GOOG) Android devices are increasingly pushing the display-size envelope, led by No. 1 phone maker in the world and Apple frenemy Samsung. For the most part, Bloomberg's report is nothing new, mainly feeding the speculation of a 4-inch iPhone with 4G LTE data speeds, two features that are practically a lock at this point.

AT&T (NYSE: T) and Verizon (NYSE: VZ) continue to build out their own LTE networks and the third-generation iPad runs on both networks, so both carriers will undoubtedly play a large role in launching the LTE-equipped iPhone.

Some of Jobs' dreams may never become reality, but the next iPhone will definitely be one of his last gifts to the world.
