Hey everyone I'm Bert and boy am I lost!! I'm 46 years old and not very good at computers,but I just got the iphone 4. Love the phone but must admit I think I bit off more than I can chew!! LOL!! I don't understand alot of the thing one can do with this phone, for example don't get how to get a ring tone into the phone much less give it to a certain caller. I've read how to do it but to tell the truth it seems too technical to understand. Guess I need a how to use iphone 4 for dummies!! HELP!!!!!!
