Were you an early adopter of the iPhone 2G? How about an early adopter of the iPhone monolithic-slice-of-tech-heaven 3G? Are you still contemplating a migration from your 2G to a shiny 3G? Is the 3G in your hand and the 2G in your nightstand drawer, collecting dust? Questions, questions. What should you do with that 2G? Read on for this week's Tip!

We've covered the "what to do with your old iPhone" question before in a previous Tip. Although you could feasibly use your old iPhone as an iPod Touch, backup phone, paperweight, doorstop, etc., money can have a strange way of changing attitudes and behaviors. If you have a strong sentimental attachment to your old trusty 2G iPhone and want to keep it that way, stop reading now and continue your 2G love-fest. If you think you can handle an extra $500 or $600 bones in your purse or wallet, then this Tip is for you.

The venerable Erica Sadun over at tuaw.com posted about this very subject about the steady rise of first-gen iPhone prices. She wrote the following:

From easy-unlocking to contract-free usage to eco-consumerism, consumers are looking for those original units and paying premium prices to get them. A majority of phones are heading outside the US for resale while growing demand at home keeps resale prices high.

It's just the good old-fashioned basic economics of supply and demand. New iPhones require a contract with AT&T and, unlike the first-gen iPhone, they can't be bought off the shelf for later activation. The 2G iPhone can be bought, unlocked, and used contract-free. Just a quick browse on eBay and you will find that 2G iPhones are selling for about $500 for the 8GB model and $600 for the 16GB model, respectively. Obviously, the better the condition, the more likely you'll fetch a higher price.

As I write this, I'm staring into my open nightstand drawer at my 2G iPhone. Do I see an older, unused iPhone or do I see a stack of Benjamin's? Needless to say, it's very tempting right now to take advantage of the current market conditions where you can get top-dollar for your used iPhone. What are you waiting for? If you won't sell, then what are you doing with your old iPhone?
