Identical in the aspect to Blackberry 8800 and the black alternative of the 8830, Blackberry 8820 of RIM takes the 8800 configuration and adds possibilities of WiFi. The basic characteristics are identical – Blackberry 8820 is a device of quadruple-band GSM with data of GPRS and EDGE, without 3G.

Blackberry 8800 is what occurs when you cross the pearl of Blackberry 8100 with Blackberry 8700 and then add a little extra.

Very similar in the face and the weight to the 8700, the 8800 additions the rich support of multi-media, the memory of microSD positive and the navigation extensible of travelling with recognition decided not to add a camera to this business-directed device.

At first sight the curve of Blackberry (also called Blackberry 8300) seems infinitely like new Blackberry 8830, but the curve is a device aimed more of the consumers and of much in manners is rather the curve of Blackberry of the Pearl.

Based narrowly on Blackberry 8800, the edition of the world of Blackberry 8830 of RIM (or alternatively the Blackberry 8830v) is a version of dual-mode CDMA/GSM of this popular device of transmission of messages.

The compounds of Dual-mode GSM/CDMA are very rare, a notable one being Motorola A840, but the this approach allows subscribers the access of networks of the USA CDMA (such as Verizon) to more common networks of GSM while wandering abroad. Yes, certain carriers in the USA (such as T-Mobile) support the GSM in the United States, but this lack of wandering functionality always put networks of CDMA-only in an unfavourable position.

BlackBerry 8707v is the first 3G BlackBerry device to market. It’s a derivative of the ubiquitous BlackBerry 8700 series of devices, and it appears to have the same functionality as the 8700, just with added support for UMTS 2100 3G data.

There are limitations with the 8707v though. There’s no WiFi, unlike some recent messaging devices, nor is there any expandable memory (internal memory comprises of 64Mb of Flash memory plus 16Mb dynamic RAM). There’s no MP3 player or camera either. Of course, many businesses actually want these limitations as it makes the device simpler to manage.

The BlackBerry’s manufacturers RIM have successfully pushed out variants of the 8700 into many major markets. Although primarily sold as the 8700g, there are also network specific versions for Rogers of Canada (8700c), Orange and subsidiaries (8700f) and Vodafone and partners (8700v). The differences between the models appear to be mainly styling and software.
