i know these have been discussed in various threads, and i dont know which ones to rely on.. 1) the battery, does it need to be ran all the way down a few times? or does it matter? 2) as far as when you hit the home button to exit apps or safari.... are they still running in the background? what metho do you use to clear them out completely? 3) any other "must do" things i should know about. my phone came with the "347" or whatever the newest version is that people were restoring to.
