Hi I bought an ipod touch off my friend because he upgraded to a 32gb so he had no need for the 16gb. He bought the apps and when i first synched with itunes the apps were still on the IPT. However on my second synch my mac hanged in frontrow so i manually shutdown. When i restarted the computer and sync with itunes the apps were gone. Has this happened to anyone else? Do i have to buy the apps?
