Want to resell your mobile device? Keep it in good shape.

I received a press release the other day with some good tips about keeping your mobile devices in top shape, especially if you’re going to want to resell it to purchase the next latest greatest thing to hit the market.  The release noted that according to one company that purchases used electronics from consumers, Gazelle, the iPhone 4 can be sold for as much as 60 percent of its original value and the Droid X can be sold for as much as 42 percent. That’s all assuming your gear is in good condition.

On a side note, Gazelle.com has an entire list of gadgets and how much they’re worth, depending on conditions. If you don’t see yours listed there, they’ll give you a quote. For example, I learned recently from them that my pre-digital-era camera lens is not worth much in today’s market.

Here are five tips from Kirk Feller of BodyGuardz (which recently changed its name from NLU Products), maker of device protection products for Apple, BlackBerry, HTC products and more to help you keep your devices in pristine condition so you can resell your used electronics for top dollar.

1. Avoid carrying your gadget and keys in the same pocket. This will prevent scratching the large screen when you inevitably squeeze through a tight spot and rub the two together.

2. Safely clean your device. Over time it will collect dirt, grime and makeup. Dab some isopropyl alcohol on a cotton swab and gently clean between the keys to avoid problems from clogged components. Here’s a hint: Hold the device upside down to prevent liquid from seeping through the cracks.

3. If you use a water bottle, make sure it’s leak-free before throwing it in your purse with your electronic devices.

4. Cover your mobile device with a full-body, scratch-free film. Films are easy to apply, inexpensive and can safeguard your device from scratches and nicks.

5. If you’re ready to upgrade or switch devices, remember to erase all data before recycling or selling your old one. Addresses, passwords and browsing history will remain in the device’s hardware even after deleting contact information. Be sure to check the phone’s manual to completely reset the memory or visit your carrier to have the phone swiped in store.
