Welcome to BlackBerry Support Forums
To update your Bold to the recent OS available from your carrier you need an active BlackBerry Subscription , without it you'll have trouble in updating ! If you insert a SIM which has an active BIS you'll be able to update your device to the most recent available for your device model.
But .. If possible avoid OS6 for your BlackBerry Bold 9700 , Bold 9700 don't have enough memory . If you install OS you'll feel issue like device freezing , lagging and you won't be able to install much application , My advice remain on OS5 .
