I have the iphone 3g 8gb, which has been jailbroken and unlocked, and am using t-mobile service. i want to know if i can use the itunes software on my comp to arrange ringtones and music. When i connect my iphone, itunes pulls up but ask me a question: 1)set up as new phone, or 2) restore from back up from "my iphone".

i was told not to update or something, thru itunes cause it will basically reset my iphone.

also how can i modify my iphone thru a pc? i donot own a mac
