Like Blackberry 7100v from Vodafone, the 7100x is an attempt by RIM to get away from its handheld-style form factor and move closer to that of the mobile phone. Neither device disguises itself completely as a standard mobile, though, because of the keypad's dimensions. Research In Motion’s (RIM) first mobile-phone-style BlackBerry, the 7100v, was released by Vodafone back in October 2004. Now O2 has joined in, augmenting its existing range of BlackBerry devices with the 7100x, which shares a more phone-like design with its Vodafone-badged rival. The 7100x measures 56mm wide by 114mm deep by 20mm high - the same as the 7100v, although the hardware design is different. The 7100x's black plastic case has a single ‘O2 blue’ flash above the screen and a small branding plate beneath the keyboard. The colour combination is rather appealing. There is a keyboard five keys wide by four keys deep beneath the screen.
