How to see the apps i have downloaded on itunes?

I have an iphone 3gs, on the same itunes account as my mums and dads and brothers iphone 4's, i was just wondering, if i download an app on my phone, can they see everything i downloaded, because i need to download a twitter app and if my brother finds out i have twitter, he will hack me how can i make sure they won't see it while on the same itunes account:/?

Well what you do is go on updates and click on purchased its pretty simple hope this helps

  • Why are all the iphone apps I have ever downloaded saved on my macbook pro? There's 60GB of iphone apps stored on my macbook pro. It is taking up a lot of space and i was wondering if that is normal or something is wrong. Would it be alright if I deleted all of it and just backed up my phone to the cloud?

  • Itunes all purchases have been downloaded for this account? So, I had an iPhone which was damaged. I have a new iPhone that will sync recent iTunes purchases, photos, notes, etc. However, it will not sync my old iTunes music. It gives me an error saying "itunes "all purchases have been downloaded for this account" (I have only 3 authorized computers) and says I should burn the songs to cds… How can I sync the rest my music to my phone besides burning my entire Itunes library to cds?
