We could well be looking too much into something, but it's fun nonetheless. Nokia has published the above photo onto its Facebook account, which appears to be teasing solar charging for smartphones. The caption reads "Sun, sun, sun, here we come!" and we're not the first to question what exactly Nokia is teasing here.
Summer's well on the way (unless you live in England) and this would be a perfect opportunity to reveal solar technology on Windows Phones. Could Nokia simply be looking forward to picnics and the beach? Possibly, but then we already know the good weather will come.
