would slackerradio.apk from either a stock 902 or 905 rom suffice? pretty sure the update from 893 to 902 does not patch the slackerradio.apk - since it can update through the market....i could pull slackerradio.apk from my /system/app folder for you. assuming you are rooted you would need to copy the apk to your /system/app folder, change the permissions to rw/r/r, reboot your phone, possibly navigate back to /system/app and choose slackerradio.apk in order to install it and then retry the update.
