Those are good prices!
I will share some info as well! The 4GB card will work with the phone, but not with the sprint music store. I found this out the hard way by trying one. I haven't tried this since the new ROM came out so it's possible they may have added support. I know the new ROM makes the music store look completely different so it's definitely a possibility! Will post back once I try one for sure, unless someone already knows the answer...
Also, RadioShack had them on sale for $29.99 if you don't want to wait for one to be shipped.
And yes, I DO work for RadioShack
