iOS Won't Update

[kangaralph]

Recently i've noticed my Macbook Air refuses to update any of my iOS devices
[iPhone 4, iPad] i have to use my iMac or a windows computer to update them.
it's gotten really annoying as my main computer is my MBA. Everytime i try to update them, they go and get stuck around 90% and just get stuck there.

I'm running iTunes 10.0.1 but it has been happening before.
Any help would be great

Sorry for double posting but i thought this would help A LOT of People.
I also had "Wi-Fi Sync" installed. it has been months of syncing on my other
macs and pcs to update my phone, hours wasted syncing tracks and videos, etc. So simply uninstall Wi-fi sync {get the uninstaller at getwifisync.com] run the uninstall terminal and type in your password. if u get it wrong the first time for some reason. shut down and power on your computer again. Run terminal again put you Pass > Restart. Need Help? Feel free to PM Me.
