Ok so, I cancelled the sync, deleted a bunch of apps from my phone (except the ones I don't want to lose data on and hope they aren't the issue) and I resynced it, so far, its further than it went in 24 hours and its only been like 24 minutes..
when reinstalling apps, shoudl I update them with itunes first then install them via itunes so i'm sure to get fresh files?
I won't reinstall all the apps I deleted as some of them I didn't use anyhow.
