I got a Kindle. Before that, I just used Kindle for iPhone to read some books.
I registered Kindle, iPhone and PC to my Amazon account. At first, WhisperSyn worked well. But now, my Kindle for iPhone can't entered. It exited after a minute.
I do not know what happened.
My Kindle for PC and Kindle 3 WIFI work well.
How can I do for this? I really need to use WhisperSyn for my Kindle for iPhone.
