Selling an iPhone 3G on eBay that has been jailbroken and more?

[Dtpl]

I have an iPhone 3G that I jailbroke. It has the background wallpaper enabled and battery percentage enabled. I upgraded the baseband to the iPad's baseband so I could unlock it using UltraSn0w. It now runs on Straight Talk service. Supposedly now that I have upgraded the baseband, you can only "upgrade" your iOS by using a custom or pre-jailbroken software, you can't use a regular IPSW anymore. It is running iOS 4.2.1 and that's as high as it will go iOS wise.

The phone is unlocked, it is 100% functional, has minor scuffs on the back, a very tiny nick on the screen (when it's in use its almost un-noticable) and has a small crack where the vibrate on/off switch is.

Can I sell this on ebay, and if so, how much do you think I could sell it for? I want to buy the iPhone 3GS or 4 but can't really afford it, so I want to sell the 3G.

Also, it would only come with the phone and a case. No other accessories or original box or SIM card.

I asked this on Yahoo Answers but I'm coming to ModMyi for a second source. Sorry if I shouldn't be posting this here, I wasn't sure if I could because it's not an ad to sell it, just asking if it'd sell on ebay or something.

Any help? Thanks.

this is both a general chat and BST post. to determine the value you should mention the storage size... 8GB, 16GB, etc
why not list the iPhone in BST section too. you can sell it on Ebay... heck, they let you sell anything on Ebay
check ebay for the same thing you're selling to get an idea how much you can get. my guess is about $50 to $100 US
