Sorry that it isn't working out for you.
I'm not sure where you live, but one thing you might consider is that there is free wifi access on the Kindle at AT&T wireless hotspots throughout the U.S. (at places like McDonalds, Starbucks, etc.). You could go there to download books onto the Kindle and then read them anywhere. My town's library has free wireless too. I used that until Amazon got my 3G set up properly.
