So, I want to make sure I understand this correctly. Minor OS upgrades can be handled with a backup to the PC, install of the software, restore of the old stuff back to the phone. Major updates (os4 to 5, or between major point revisions) require a clean install. If I do a backup and restore, apps and data are loaded. If I do a clean install, I can get the apps back but the data is lost. Is there any way to backup the data independently when performing a clean install? If not, this seems like a major stumbling block/oversight. Hopefully I'm missing something.
