Before the BlackBerry 5810 came along in early 2002, Research In Motion's devices were best known for their data capabilities: Push e-mail technology, Organizer features, and thumb keyboards. The 5810--the first BlackBerry to offer voice capabilities--changed that perception. This device added a GSM cell phone to the package, albeit one that required the use of a headset (it lacked both a speaker and a microphone).
The very first BlackBerry device with a phone, the boxy 5810, wasn't a looker even at the time. Sure, you got enterprise e-mail support, text messaging, and a WAP browser, but without an integrated microphone or speaker, you had to attach a headset to make calls. Needless to say, that was a drawback.

2012 iPhone 4Gs
The display of the iPhone 4 features an LED backlit TFT LCD capacitive touchscreen with a pixel density of 326 pixels per inch (ppi) on a 3.5 in (8.9 cm) (diagonally measured), 960×640 display. Each pixel is 78 micrometers in width. The display has a contrast ratio of 800:1.
The iPhone 4 is the first iPhone model to have two cameras. The LED flash for the rear-facing camera (top) and the forward-facing camera (bottom, left of speaker) are not present in older models.
The iPhone 4 is the first generation of iPhone to have a second microphone used for noise cancellation. It is located on the top of the unit near the headphone jack; the main microphone is on the bottom left.

2022 Conceptual Wrist Phone
Visualizing a cell phone’s design may depend only upon your preference, as cell phones will likely be constructed of flexible, clear material. The entirety of the device will serve as a screen and a touch-screen, responding far more effectively to our commands than they do today. Due to this versatility, the entire device in effect can be customized – no need for cell phone “skins” or cases anymore. Speaking of cases, these phones’ surfaces will be much more resistant to scratches and dings than current screens and may even feature recently-developed technology that allows for the device to actually repair itself using a polymer that “self-heals”.
By this point, cell phones will have become the ultimate and only communications and assistance device in our portable lives. Much as we have seen alarm clocks, calculators and MP3 players recede from use thanks to the cell phone there will be even larger implications in the coming decade. Soon, phones will be able to act as our wallets, all-in-one medical devices, and may even replace our current computing systems if a hyper-efficient projection system can be developed in the next few years. It is very likely that these devices will feature projection keyboards that can be used on a surface.
