BlackBerry Tour 9630 Review
BlackBerry Tour 9630, unlike other BlackBerry’s models, for example, Curve, Bold or Storm, is aimed more at the mass consumer market than business users. This is clearly visible in the set of functions available on BlackBerry 96530, and the emphasis that the manufacturer put on multimedia support.

BlackBerry Tour 9630 does not offer Wi-Fi. It supports the EDGE technology (4 ranges), CDMA EV-DO, UMTS / HSPA. With BlackBerry Tour 9630 you have access to the Internet service shop with applications (App BlackBerry World). According to the latest trends BlackBerry Tour 9630 offers access to social networking sites Facebook, MySpace and Flickr.
BlackBerry Tour 9630 has a QWERTY keyboard and a classic 2.4-inch screen with a resolution of 480 x 340 pixels. Its dimensions are similar to the screen dimensions of BlackBerry Bold (480 x 320 pixels) and Curve (480 x 360 pixels). The manufacturer ensures, however, that by increasing the density of pixels per inch, the display in Tour is the largest among all available in RIM's devices.

BlackBerry Storm 9530 Review – The first BlackBerry with touch screen
BlackBerry Storm is the first BlackBerry device with a touch screen. It is available only in the U.S. Verizon Wir29eless, though sometimes you can find it at auction portals (Amazon.com, Ebay.com)

BlackBerry Storm 9530
BlackBerry Storm 9530 is characterized by innovation in a broad sense. BlackBerry Storm 9530 is equipped with a 3.2 megapixel camera with auto-focus option, and - as it is already a standard solution - a video camera.
One of the undoubted advantages of the device is very clear, high contrast display. In addition, BlackBerry Storm 9530 deserves applause for a very sensitive high-resolution camera. You can also find the support for Visual Voicemail [as in the iPhone], enabling listening to voice mail messages, deleting them, and recording a new greeting.
However, there are still some glaring problems with BlackBerry Storm 9530. Even after upgrading the operating system with Verizon new OS in many applications it tends to become extremely dawdling. Another drawback - what many may wonder - is the lack of Wi-Fi and a QWERTY keyboard.
Problems related to software, according to Verizon and RIM, will be gradually corrected through further software updates. What is interesting, WiFi receiver is to appear in future versions of Blackberry Storm.
