before i installed the update, i got a prompt telling me it would back up data/settings etc so i just thought that it would do it. after update everything seems to be their. my app notepad still has my text their etc..my phone is new so ive not added any bookmarks or anything but my wifi was on still, didnt need to re enter the ID key. i guess it just does it for you, their must be a folder on sd card that says data or something.
