Yes, Amazon's service is Sprint, which is OK here. My phone is AT+T, which is marginal, unless I am upstairs.
I do think I will wait on the Kindle for a while anyway, as I can see a lot of things in the reviews that could very well be fixed in the next version. Like the shades of gray, and the font sizing problem and other little potential improvements.
Though it sure would be nice to have a load of books in one little gadget to take on a trip. When we do go to islands though, we always take a load of paperbacks and when we finish them, we leave them behind for others to read, or donate them to their tiny libraries.
In poor places like Belize, we left our clothes, towels and stuff for the people too. And left our American peanut butter, as its a delicacy in parts of Belize.
