1. Is it necessary to restore as new when doing updates? 2. I have my email on my phone set to manual. After updating, my mail appeared to have been fetched automatically as new messages appeared but no settings changed. 3. Iphone2,1_3.1_7C144_Restore.ipsw appeared in my trash. Is that normal and what is it? 4. I turned my phone off after the update and then turned it back on. My battery meter went from 91% to 94%...unless my eyes were playing tricks on me. I have not had previous battery issues. Thanks for your time and answers.
