Over the weekend, i just jail-broke my kindle to install a Chinese themed screen saver. During the process, i learned that previous Kindle edition allowed user to customize the screen saver with images of their choice. With Kindle 3 (even Kindle 2.x?), however, the screen saver is locked down. One has to jail break it before installing her own screen saver.
It seemed a silly product decision.
Until this morning when i read this: Amazon to Sell the Kindle Reader at a Lower Price, but With Advertising Added.
