A complicated syncing and backup question needing a (hopefully) simple answer
I need help from somebody to answer a few questions I have (I have searched around without finding any direct answers to the questions I have - thank you, thank you, thank you in advance):
OK, here’s the deal… I have a 16gb iPhone 3G. About 6 months ago my laptop died and I purchased a new one (both using Vista, but I doubt that really makes much of a difference). Being an app addic I have never had the “Sync Application” box checked on my new computer... Upon receiving the new laptop I “Transferred Purchases” from the phone to the computer and backed it up. Whenever I download a new app on my phone I transfer the purchase to my laptop and I backup my phone every other day or so (right click, “Backup). I thought about syncing my apps but get the message “All existing applications and their data on the iPhone …. will be replaced with applications from this iTunes library”. On first glance this sounds OK to me because these are all the same apps (with a few extra apps in the library that were deleted off the phone but not out of the library), but this got me to wondering about a couple of things…
1. I have too many apps with sign-in data, friends, lists, game saves, and lots of other info to even think about losing the app data associated with these apps, so I am not even tempted to experiment to see what would happen if I do sync the applications without some type of confirmation that all will not be lost. If I do check the box “Sync Applications” will I lose any app data?? The app data should be on my computer from my most recent backup, right??
2. Summer is coming soon, meaning new iPhone time (woohoo, forget the iPad, I am excited about what might be on the next iPhone)… Anyway, since I do backup regularly, when I get a new phone (even if it is just a 3GS a friend gives me), should it be simply a matter of plugging it in and hitting “Restore from backup” to get all my old apps and their data onto a new device?? The reason I am confused here is that my backup folder is 462MB in size but my iphone tells me the following - Photos 151MB, Apps 2GB, Other 538MB.
My biggest worry here is that I don’t want to lose any app data on my phone by doing something stupid and checking the wrong box. I'd also like to confirm that all that should be needed to get a new phone (or old phone if it crashes) into the same state as my current phone is in is to "Restore from Backup", taking into account my just mentioned situation that my apps are not synced...
Thanks to whoever knows the answer and is kind enough to share some straightforward thoughts (and might be willing to humor any follow-up questions I have).
