I have come to the conclusion that I would like to ugrade to the new iPhone 4 despite the reception issues. I have become too comfortable with the iPhone to switch to another brand and the standard 3G is just too slow with the new OS4. Additionally, I have been eligible for an upgrade for a while now.

After browsing Ebay, it seems that I can easily dump my 3G and pay for the new one while putting a few sheckles in my pocket at the same time.

What I would like to know is the following:
-What are these things worth (ballpark)? They vary A LOT online. If I can get $200 for it and cover the cost of my new one I will be a happy camper, but if I can get more, great.
-Should I unlock it first? Does it need to be? My phone is not jailbroken or anything.
-Should I clear the memory prior to shipping beyond what iTunes allows for? I am a little uncomfortable with shipping my phone to someone after I have been putting through tons of sensitive info into it for a while now. Doing a restore seems sufficient but you never know...


Anything else I should know?

Thanks in advance, any help is much appreciated.

 

Just list in your ad the shortfalls and failures of the iPhone 4, and yours will be sold like hot cupcakes

 

price? depends on the condition..... there is a guy in the buy/sell forum here listing a 3g 8GB iphone in perfect condition for $200....

i wouldnt bother unlocking/jailbreaking it, unless the buyer specifically requests
it....its not very hard to do anyways, let them deal with it themselves.....

You limit your target audience by not jailbreaking/unlocking it. Many people that are already looking at an iPhone can easily just go to AT&T, sign the contract, and walk out with a new iPhone for the same price. I sold my gen 1 iPhone back in Feb for $200. Some people (current AT&T customers) do not want to pay the data plan for the phone, and T-Mobile customers just want a phone that they can place the SIM in and it will work. The jailbreaking/unlocking part is pretty simple, but getting the phone to come on without touching AT&T's Edge/3G network is a little more involved. Just my .02.

 

I'm selling my Vaja case on eBay if anyone wants it for the 3G. Just picked up the iPhone 4 a few days ago so I no longer have use for it.
