I downloaded an app "Find my iPhone", but it didn't get onto my iPhone 3GS. I plug my iPhone into my PC and start up iTunes. The app is showing "Downloaded" in my library. I go to my device and it's nowhere to be found. In iTunes, under the device/app tab, my iPhone shows up by is "greyed" out. I can't move around apps or do anything I used to be able to do. I click on the "Snych Apps" box and it's asking me to replace all my iPhone apps with apps from the library. If I click yes, it seems to mess up everything on my iPhone. The box is checked to Automatically Synch new apps.
How do I get onto my phone in iTunes to change around my apps? I want to put some in folders, move them around to different pages and get the new download on the phone. Never an issue before. I'm guessing something with update to iOS 5 and iCloud.
