People have been clamoring for a decent camera, a camera flash, a front facing camera since the very first iPhone came out. It seems like with iPhone 4, they delivered on every single major hardware feature people asked for, except for a 4.3 inch screen. Other than a 4.3 inch screen, I can't think of what hardware improvements apple could possibly offer in the iPhone 5 to get all but the most tech obsessed to upgrade next. Do you think they will do something completely unexpected and out of the left field, like a 3D screen akin to the Nintendo 3DS? What can you think of? Xenon Flash instead of LED Flash? Micro-SD Card slot with access to a file system that lets you use both the phone, and the SD card as an external hdd? A Camera Shutter and a Shutter Button and Screen Orientation Lock? Analog Zoom for the Camera + Even Bigger Lens/Larger CCD for even better quality pictures and videos? A 4.3 Inch Screen? A 4G LTE Antenna with support all of the 2G, 3G and 4G frequencies worldwide and the ability to use Verizon, Sprint or T-Mobile? Bluetooth 3.0? A Built in Projector!? SD Card Slot? Dual Speakers like the iPad and support for 3D surround sound? Reduce the size of the bezel on the top of and on the bottom of the phone? Center the front and rear cameras on the phone? Along with a bigger screen, put the antennas back inside the phone case to prevent interference (would also get rid of the seams in the metal border around the phone)? A CPU Upgrade (to the dual core Cortex A9 processors)? A GPU Upgrade (to the SGX545)? Siri Voice Controls hardwired into the phone to allow you to launch apps, and control apps by voice alone? Sync and stream from AppleTV/iTV wirelessly via cloud? IR, FM Radio & Transmitter, HD and DAB+ Radio, RFID, Pedometer? Wireless Payment Chip (ex: Paywave or Paypal)? HDTV Tuner/TV Reciever and Mini HDMI Out? A Smaller Bezel Above & Below the Screen? 64GB/128GB? Light Peak? Super AMOLED and a 3D Screen like the 3DS? Touch gestures/sensors on the corners of the phone and/or on the glass back of the phone? Replace home button with a touch sensative area to make the phone even more aesthetic and symmetric (Get rid of the round indentation below the screen and replace it with an unindented, unmarked button) 8 MP Camera/1080p Video Recording? Maybe if those features end up in the new iPhone it would be enough of a leap to warrant an upgrade.
