Mountain Lion and IOS 6

 Several years ago My family became true Apple Computer fans. Started simple with "Nano's", progressed to "Itouch" and then "Iphone" and eventually Macbook pro! If Your an Apple user then You understand the typical progression with operating systems and in this case upgrading from Lion to Mountain Lion on the Macbooks. Upgrading to Mountain Lion or OS 10.8 is a  $19.95 purchase thru the Mac store. I think a direct mail DVD is more money. This particular download went well although the little tiny progress bar at the bottom under the Mountain Lion icon is really hard to see! Follow instructions and have tons of patience-- this took about 8 hours thru a DSL connection at 2.5 meg!! The download size is about 4 gigabytes!
  The mobile operating system -IOS 6 is a free upgrade done thru Itunes for ,Iphone and Ipad and other apple devices. I upgraded a iphone 4S, iphone 4 and Ipad 2 & 3 with no problem. It did need the latest itunes-- 10.7 so be prepared for a double whammy! Itunes is about 80meg and IOS 6 is around 900 meg. It adds up at slower download speeds.The iphones I did thru itunes and the ipads thru Icloud. All of these went well and the users are happy!
 I next tried My old jalopy of an iphone- a 3gs running IOS 4.3. I first read reviews on the internet and they were mixed. I decided to still chance it. All seemed to be going well until it was time to reload the phone from the backup. I had a write to HD error!! Oh boy. Phone seemed dead and after a very long time I bit the bullet and disconnected it from the PC. Yup -dead phone. Rehooked to Itunes and thankfully I saw the Apple logo eventually appear and a load bar start. It did not like the most recent backup so I tried a previous backup and that kind of worked. It finally finished loading but I was missing most of My apps and information. Under settings I noticed it now did say I had IOS 6 loaded so it was partially good.
  I tried re-syncing and was surprised to see now most apps did reload, although in a haphazard fashion on multiple screens. I started moving the apps between screens to get them on fewer screens and then re-synced again and finally had My phone recognizable!! It also appeared to be working OK with the new features of IOS 6 available. It will be soon time to trade in this model for a new one-- but not now!!
 Would I try upgrading a 3GS ? I would only try after following the upgrade route of IOS 5 first. I can't help but think that might have been part of the problem along with a partially sick PC( a windows machine!). It also is OK to try Apple support-- I've used them a few times and they are very helpful and don't make You feel stupid!!!
  good luck upgrading-- final result is worth it!!
