yeah its old news I had it on my 8900 and it says its only available for us users but UK users can download it and access there books (you just can't download any new books via app)
officially there is no app for os7 but there is a gud work around on the forums to get it working (simply download to your phone and when you get the start splash screen plug into your computer and the sync charge etc option screen pops up and it allows u to get through to your books and any time you open up afterwards it should open without a problem)
concerning kindle on the playbook, with the android player the android version works well so might be an option
I went to amazon.com to buy something and then BOOM!!!
I see this..... Amazon.com: Kindle for BlackBerry - Read Kindle eBooks on your BlackBerry
*It looks like Amazon and BlackBerry finally made an agreement. Kindle App is now available to Blackberry Smartphones and soon the PLAYBOOK!!!
*I don't know if you guys have heard this before...but i just found out
What the frak...r u serious. This is a year old link.Did you even freakin do a search on the forum about the kindle app..? There won't be one.
