Name a few so folk can guess if they are forced by your carrier. Also, I wonder if you are any cloud sync.
When syncing with itunes it is forcing 40 recently downloaded apps to reinstall on my phone even though I have deleted them repeatedly (including deleting the backup and creating a new one). My phone is an iphone 4s 16gb and I am running itunes 10.6.1 on a 2008 macbook with a 2.4 ghz intel core duo and OSX 10.5.8. My itunes library is installed on and external WD 1tb hard drive. How do I persuade it to stop installing these apps? They take up space I can't spare and prevent me from syncing because they are using more memory than I have available
