ok. I got my phone replaced because of wifi problem (most likely overheating) but I learned a couple things. -they won't transfer the information from the iphone to the new one for you. -upgrade your phone now if you haven't already. Otherwise they'll upgrade there in store which they did with me. If the wifi starts working again (which for me it didn't) you might get screwed if it's just temporary = 1 more trip to store. -Flashing your phone instore will totally wipe it's data. -your new phone won't be retail. most likely refurbished -you'll lose your screen protector. -after you replace the phone, make sure u test wifi, less you'll have to run to the store again. Backup the below, you'll have to restore it yourself. -Make sure contacts, calendar, etc or backed up. -Make sure your pictures are backed up, itunes does not do this in windows systems. Genius B guy said you'll have to use the microsoft camera wizard.
