I can't install app update from my phone. I keep getting message saying "unable to download". How can I fix this? I also keep getting app errors while syncing. I have to uncheck the the app via itunes sync the phone the recheck the app and sync again. How do I get rid of these errors?

Do yourself a huge favor. Update your apps on ITUNES (your pc) not your phone. Your issues will go away. And yes I know you are supposed to update from your phone, and yes people do it all the time with no problem, but do yourself a big favor: Update your apps on ITUNES not your phone, than of course sync the updates over.
