I will wait a few more years and collect more data before going back to 2007... then along the way, I'll realize that I should bestow all the edge to community, rather than Nokia... so I'll come back with 10th gen pocketable computer software stack, along with plans for quad core ultra power efficient ARM platform... and the latest power cell technology...

....arriving in 2007, I'll come to realize that the 2027 sports almanac in my backpack worths more than all the technology blueprints I have brought back instead. So I'll sell off my delorean and go to Vegas with the almanac.

Little did I know that history never repeats itself in a different multiverse... and as I gambled off my last dollar bill... I should've noted that the iPhone was introduced as the first fully opensourced smartphone, here.
