I recently bought an SSD and in an effort to save space on it, moved my iTunes library (music + mobile applications folders, etc) to an external hard drive and in iTunes pointed it to that location. The music seems to work fine, however the issue is with iPhone apps. From what I can tell, it can detect apps that need updating, however when I download the updates, it'll send the .ipa files from the /external hard drive/music/itunes/mobile applications folder to the trash, however it downloads the updates to my /ssd/music/itunes/mobile applications folder. What I had been doing was moving those from the SSD to the external hard drive's mobile applications folder, however it looks like those app updates are not syncing properly. It seems to be hit or miss in terms of whether the updates actually get on the phone, although I am not 100% sure--I could have just forgotten and synced with the apps still in the ssd's mobile applications folder. So I guess the bottom line is, what's the deal with regards to getting my iPhone apps working and syncing properly when I have my itunes library on an external drive? How do I go about fixing the problem that now I have the updated apps in my mobile applications folder on my external drive, but they aren't installed on the phone? I tried dragging them to the ssd's mobile applications folder, however they still wont sync. Any and all help would be very greatly appreciated, thanks!
