I had the Sprint Hero since launch day, sadly i had to exchange the phone for a new one... Ever since I got the new phone I been trying to load back the 3 person HTC People widget with no luck. Is there something that could be preventing, the only thing from the old phone that transferred over was the number and th SD card... I cant figure out what is preventing this... Any help would be great!
It will whip your phone back to a fresh factory install. Any apps you downloaded from the market should be retrievable again, but people have run into problems with this. If her email, contacts, calendar are synced with google then those should come back when you resync. Any saved scenes and widget customizations will need to be redone. Ringtone settings etc will also be gone.
I believe that most of the apps keep their data on the storage card so that stuff might be safe, for example if you are using AK Notepad the notes should be kept on the SD card. You'll want to research things like this before you do it
