M.I.C. Gadget reports that they’ve gotten hands on with an iPhone they’re pretty sure isn’t an iPhone 4, but possibly an updated model that includes a 3.7” display, and the same proximity sensor as the white iPhone 4. The new display is nearly edge-to-edge, bumping up the screen size but not nearly large enough to be a 4” display as previously rumored. M.I.C. Gadget also speculates that it may have an A5 processor (a prototype model) that game developers are using to build games. Strings in iOS 4.3 revealed that the iPhone was slated to receive the updated processor, and recently a white iPhone was rumored being tested on T-Mobile’s network packing an A5 processor. A bigger screen has been seen floating around on leaked design documents in the past.

This is My Next’s Joshua Topolsky speculated that the iPhone 5 (the model shown above has be dubbed the iPhone 4S) would feature a 3.7” display, and include a tapered design and would be completely unlike the iPhone 4 in design. This leads me to believe either the model M.I.C. Gadget came across is a prototype unit with a fitting for the new display, or there will be a spec bump for the iPhone for the summer with a completely new iPhone landing this September (I wonder if we could see two new iPhones in the same year, with the white iPhones having taken so long to be reformatted for the 3.7” displays). I don’t think that’s a possibility, but clearly sources are seeing multiple iPhone models either in the prototype stage or are seeing design models beyond what we think the next iPhone is.

The next iPhone is rumored to be adopting NFC technologies, inductive charging, and was previously reported to feature a similar design to the iPhone 4. Verizon’s CFO Fran Shammo recently noted that the next generations of iPhones could be world-phone enabled, and we should begin seeing the launch of the white iPhone 4 on April, 27th.
