Is the 8707 the last of the classic BlackBerry models that use the wheel for controlling the unit? How hard is this particular line to find? I know it has 2100 MHz 3G which can be an advantage when in places like Japan & South Korea where there is no GSM. How long is battery life on this model when using an extended battery like what is offered by Seidio? Does anyone here think it's worth paying the extra money to hunt down an 8707 vs one of the other 8700 GSM models?

Are there other old BlackBerry models that might be better to get if one really is looking for one in the classic style, without the bells & whistles but does work in many places in the world?
