What is the difference between BlackBerry Bold 9000 and Bold 9900 Touch Screen?

The Blackberry bold 9000 and the bold 9900 touch screen are two different models of the Blackberry series. The Blackberry bold 9900 touch screen, however, is a big leap of evolution that is atypical of RIM. The first major difference between them is the Blackberry version of OS that they are using. The Blackberry bold 9000, which is the older model, uses the familiar blackberry version 6; while the newer Blackberry bold 9900 touch screen makes use of the revamped version 7 of the Blackberry OS.

Most other differences that occur are as a result of this first earlier stated basic difference. Though there are several other Blackberry series that have a touch-sensitive display, the Bold 9900 touch screen is among the first to feature this touch-sensitive display, while the bold 9000 doesn't have this feature. The bold 9000 is equipped with a 600Mhz processor and just 128MB of RAM; while the bold 9900 comes with a 1.2Ghz processor and a RAM of 768MB.

The significant difference between bold 9900 and bold 9000 is its hardware. It is an entirely new hardware specification compared to bold 9000. The processor, memory, display, weight, and design have changed. Bold 9900 comes equipped with a touchscreen as well as an optical touchpad, whereas Blackberry bold 9000 only touch ball was there.

Blackberry bold is one of the best -selling blackberry devices, mostly in the corporate market. 9900 is the latest addition to the bold family. The phone comes with a wide qwerty touch screen and an optional optical trackpad. Since bold comes with full qwerty keyboard finger movements, it will always be in the lower part of the phone.
