Posting on their official Twitter account, Nokia's Ovi Store team have widened the qualifications for re-downloading purchased content, restoring the situation to how it was immediately after the system was trialled a month or so ago. They posted: "OviStore Redownload update: Re-DL poss on replacment device if same model or compatible one". So, as long as you're signed into the store and have a device that's compatible with the one you bought the original item for, re-download should be possible. Which all sounds eminently sensible - at last.
Having, essentially, the re-download system locked to just your Ovi username brings the Ovi Store into equivalence with the Apple and Android app stores - which I've long felt is something that needed to be in place. Now - how is it working out for you in practice? I imagine there are crossover pains for people buying items before this latest store software update?
