Apple needto add a feature where you can just drag and drop on app onto your iPhone without it needing to sync/backup etc. Its highly annoying when you have a dev build of sumthing or downloaded an app off itunes on your computer instead of off the mobile store.....
But how would they implement that? Yes, it's annoying and especially for me because I have this sh*tty computer and iTunes hangs whenever it syncs so I can't use it (After it's finished syncing it's alright)
They should just make a dev section in iTunes where devs can upload their betas, and have it password protected, then you can just dl them like a regular app. How plausible that is? No clue.
Well the devs would still include the provisioning file that allows only the specified UDIDs play the game.
I think that's a good idea. You can do it with music, tv shows, video's, why not apps? I don't have a lot of storage on my PC so I had to put my music/videos on my ipod and iphone, manage them both manually, and take the music off my hard drive to have space for apps. I'd love to just back up my apps (to my ipod classic which has about twice as much total storage as my PC) and take them off my hard drive to have more space, and only download updates and stuff.
