Hi coachhip (and to others who have posted):

I have a skype with one of my friends in Nicaragua tomorrow.  We will discuss all the phones mentioned on this thread, including your iPhone 3g.  I'll have a better idea about what he thinks he can get for it.

Thanks to all who have posted.

To those who are reading: if have a used smart phone and you want to see if I can get something for it, it doesn't hurt to ask!

Thanks!
