Been a while since I've posted here, but thought you all might be interested 
in a new tool I've added to the site at FreeSimcards.info which allow you to 
compare the money offered for your phone from a number of recycling 
companies. Just select the make/model and hit search, you'll get a pop up 
showing you the offers.  Here's a the link to the page:

btw if your looking for free simc ards the site is packed with them too :)

Thanks
