My 3G works fine for SMS, Email, incoming calls, internet, WiFi, skype, but outgoing calls fail every time. The AT&T store couldn't fix it and told me to go to the Mac store, where "they will most likely replace the unit, since it is still under warranty". I just have the regular 1-year warranty that comes with the phone, and it's still valid since I bought it in December. I have a few questions about what my options will be: 1) Has anyone had this problem, where the phone stops making outgoing calls, but does everything else? Was the solution to replace the phone, or did they do something else? (ATT already tried changing out the SIM card, and it's not a billing issue) 2) do they have a way of tracking how many times it's been dropped, and are they going to try to tell me that the phone not working is my fault, and is thus not covered? 3) if they give me a new phone, will they give me a brand new phone, or a refurbished one? 4) If they give me a new phone, could upgrade to the next generation (if it comes out in the next week or two), or could I upgrade from 8 GB to 16 GB, or do would I have to get a 3G 8 GB again? 5) Once I have the new phone, would the warranty clock re-set (I've had my phone since December, so if I get a new one in June, is the warranty on the new phone good through December 2009, or June 2010) Thanks for the help!
