UPDATE WITH FIXES

Sorry for the wait but...
I have tested this Browser.apk and it seem that the JavaScript and FC issues have been fixed!!! Not 100% sure but my testing has led me to believe so!!!
Flash update included
I will also upload the raw Browser.apk for those who would like to tinker with it on their own.
