I have a 3G Iphone. I'm old school. I know I don't use this phone right, and I don't use it for 99% of stuff I could be using it for I'm sure. Every time I sync my phone to my itunes it asks me to do a software update....I'm afraid to do this update because I've had people tell me that downloading the updates on the 3g phones will jack them up. But then I have people tell me I have to get the update because I'll be able to multi task and stuff. Who knows something about this that could tell me what doing the update is really going to do to my phone?
