MonkeySee.com, a site devoted to professionally-produced and user-generated how-to videos answering an array of questions, has just posted a new video titled "How-To Upgrade to the 3G iPhone." The short (3:46) video is narrated and produced by one Joshua Dubois, a videographer and editor.

It shows you what to do with old iPhone - should you be upgrading - and how to import your contacts to a new 3G iPhone or newly acquired original iPhone. The video also walks you through the steps necessary for erasing your data from an old iPhone and popping out the old iPhone's SIM card, for example. Another section explains how to import contacts from an old 2G or 3G phone (if you're a current AT&T customer)to a 3G iPhone.
