I have two issues. I am looking for people that have had experience in these fields and could possibly offer advice on whether I should make the appointment and follow through with Apple Geniuses. 1) My MacBook's screen flickers a bit for several minutes when first turned on or brought out of sleep mode. It is about 13 months old and it just began about a month ago. What would the Apple Geniuses be able to do about this? Is there an easy solution? 2) I have a 4GB iPhone and I would really like to get an 8 or 16GB. Obviously this was just wishful thinking until I dropped my iPhone today for the first time in nearly a year and it got a really ugly scratch from the concrete. Would it be possible to trade in my 4GB and get an 8 or 16GB? I've heard of people getting refurbished phones for like $250 or something, is that my only option? Also, do the Apple stores even have first generation iPhones anymore? Any help would be greatly appreciated, thanks in advance.
