There are several differences and similarities that are depicted by the blackberry and the iPhone. With this background, this paper will compare and contrast the blackberry and the iPhone.

Components
The Blackberry has an LCD clickable touch-screen (Whittaker, 2009) on the other hand the iPhone equally has a click and touch-screen. The main difference is that the iPhone screen has been specially made to be scratch resistant and has an enhanced visibility. In addition to this the iPhone screen is itself is 3.5-inch with a touch-sensitive display with a resolution of about 320-by-480 pixels. Another distinguishing factor with the screens is that in the iPhone an Apple branded component which is the Broadcom BCM5973A that mainly provides the IO controller that is used for the video interface is linked to the touch-screen. With the blackberry the screen is detached from this feature (Cunningham  Turner, 2009).

The blackberry has a memory that is predominantly flash and RAM-random access memory while the iPhone equally has a flash memory. The distinguishing fact is that the iPhone memory is in a position to accommodate several chips but the blackberry is custom made especially for execution of codes. For instance the chips that can be found in the iPhone include the 64Gbit Samsung MLC NAND flash, the Intel 32MB Wireless Flash Memory, Wolfson audio chip and the Infineon multimedia chip. The Intel wireless flash has 32MB neither of NOR together with 16MB of SRAM that is used for the execution of codes. In addition to this, the iPhone has a greater capacity in terms of memory than the blackberry for the same reason. This is bent on the fact that the iPhone has the MLC NAND flash (K9MCG08U5M) (My-Digital-Life, 2010) memory that is vital in the storage of items like videos, songs and pictures. In the case of the 4GB version of the iPhone Samsung provides the K9HBG08U1M. The figure illustrates some of the internal features of the iPhone.

The blackberry has a Bluetooth GPS (Whittaker, 2009), Bluetooth Barcode Scanner, Bluetooth Headsets, Bluetooth Keyboards and Bluetooth transmitters in some of the models, whereas the iPhone has slightly different Bluetooth applications and features. A case in point is the Marvell chip 88W8686 is a 90nm WLAN device that is meant for the wireless protocol 802.11bg support (maltiel-consulting.com, 2010). This chip is found in the Wi2Wi 802.11  Bluetooth System that is located in the Package Solution for the iPhone. However the CSR BlueCore is a Bluetooth chip 4 ROM device. This device is used by the iPhone and the BlackBerry Pearl 8100 as well (maltiel-consulting.com, 2010).

The processor used by the blackberry is a 32-bit microprocessor conversely the iPhone uses an ARM processor that has a core speed of at least 620MHz thus it is very sufficient. In addition to this the processor has ample CPU headroom left even with multiple applications being run on it. Further more the iPhone Samsung processor is a three stacked die package with an S5L8900 alongside two 512Mbit SRAM dice. Other features that are evident in the iPhone is that it has GPS Transceiver-Infineon which is also a feature that can be found in the blackberry as well. Further more the blackberry has an application that allows for camera functions to be easily displayed, on the other hand the iPhone has a Camera Module which is specifically manufactured by Altus-Tech, Primax, Lite for this iPhone.

Functions
The iPhone has the IBooks function which is a new version of the e-book platform within the iPad.  IBooks are able to sync a users place within a book when the user is switching from a given mobile Apple device to another, whilst the Kindle for the Blackberry has software that gives instant access to a collection of eBooks. The distinction comes in the fact that the iPhone uses a feature that is more advanced when compared to the blackberry.

Email is a feature that is found in the iPhone. The email here has a merged inbox view, it enables that user to switch between inboxes very fast and to sync within more than one Exchange accounts. It also has a threaded messaging. Further to this there is an in-app attachment viewing. On the other hand the black berry has the email (Whittaker, 2009) function but the distinctive feature about the email feature in the blackberry is that it uses a push technology which constantly monitors e-mail giving information if a new mail has arrived and has a filtering engine in its software which helps the user to avoid spam messages. In addition to this the blackberry allows its users to make use of other programs that allow it to be used in getting and acquiring updates from updates from e-mail messages through which they can view data, make a phone call or log in to a service.

Calendar Access is part of the organizer applications that come with a blackberry. The organizer facilitates the management of all information and communications from the device thus sufficient management of all activities. On the contrary, much as the iPhone has the calendar access within its organizer applications, the activities that can be done with the calendar access are more. For instance the user is able to create and even edit events that are in the calendar directly with its Event Kit. In addition to this it is able to set up start and end times, create recurring events and also assign the same to any calendar on the device.

The BlackBerry components usually remain behind the corporate firewall and all the application as well as mail servers as it communicates with the handheld units via the firewall through the BlackBerry infrastructure. This ensures total organizational information security. On the other hand the iPhone is at the discretion of the user. This is the main reason why organizations prefer to employ the services of the blackberry more than those of the iPhone. In addition to this the structural differences also make the blackberry more preferred for business and corporate functions.

Operation
There is a huge difference in the way the iPhone operates in relation to the blackberry. The iPhone mainly relies on the CPU and the GPU while the blackberry relies heavily on its enterprise server.  A case in point the CPU is based on the ARM1176JZF-S core (Shimpi, 2009). The CPU of the iPhone runs at 412MHz in order to save power, much as the core is in a position to run at 667MHz. The CPU of the ARM11 is a single-issue in-order microprocessor that has an 8-stage integer pipeline. In addition to this it has a 32KB L1 cache in which there is 16KB for instructions and 16KB for data but there is no L2 cache. The ARM11 CPU within the iPhone equally has a vector floating point unit but the SoC contains a separate GPU that is meant for 3D acceleration. The figure illustrates the SoC housing of the GPU.

This core is high clocked and advanced 486 with extremely low power. With normal load this CPU core consumes about 100mW. A PowerVR MBX-Lite GPU is the core that is paired with this CPU and is a form of DirectX 67 class GPU. The figure shows a power VR.

The GPU is very simple and is built on a 90nm process but does support hardware lighting and transform. The MBX-Lite within the iPhone is structured like the MBX but it is optimized for power efficiency making if significantly slower about 60MHz. when the MBX-Lite is on the same chip as the GPU and CPU in the iPhone, the SoC occupies 128MB of DDR memory so in the real sense all items are ion a single package which is physically smaller than the Atom of an Intel (Shimpi, 2009).
Considering the BlackBerry Enterprise Server, there are several server components that enable the black berry to function as required. There is the BlackBerry Router which is designed to specifically route data like the intranet data, email messages, browser data and organizer data. It connects the BlackBerry Infrastructure using SRP to the BlackBerry Enterprise Server through the wireless network. The router is able to reach the BlackBerry Infrastructure via Port 3101 on the firewall. There is also the BlackBerry Dispatcher which is a medium through which all communication between the BlackBerry Enterprise Server and the components of passes. The BlackBerry Dispatcher usually decrypts and then compresses all the BlackBerry data. Others include the BlackBerry Controller, BlackBerry Policy Service (media.wiley.com, n.d), BlackBerry Messaging Agent, BlackBerry Attachment Service, BlackBerry MDS Services and the BlackBerry Manager.

Conclusion
As depicted, the blackberry and the iPhone have several similarities when it comes to their structure but there are slight differences in the features that make up the two gadgets. It is upon the users to know exactly what they need and the financial implication before endeavoring to purchase any specific gadget. It is however important to note that the manufactures of these two gadgets are still developing and including new features to meet the needs of the clients and demands.
