If I were you I'd avoid using the phone altogether for taking shots of items that you want to sell on eBay and take the shots of the item using a decent digital camera instead. You don't necessarily need the type of camera with such a high specification that it would appeal to a press photographer - a relatively inexpensive compact camera, such as a Canon Ixus, ought to do the job.
Once you've taken the shots just take the SD card out of the camera, insert it into the cardreader slot on your laptop and upload the photos to your desktop, or wherever else on your laptop you've decided to save them. That way when you come to set up the listing you can just locate the folder that you've saved the photos in and upload them to the listing. It's far more straightforward to do it that way and it's a lot easier on the eyes as well.
