When Apple brings out a new phone, my advice typically is to wait a couple of months for the problems to surface, and then they will either be fixed or known and you can make a more educated decision. However we haven’t seen the number of problems with the latest iPhone since, well, ever. To summarize, the antenna is badly designed, the signal strength software is inaccurate, the proximity sensor that’s supposed to keep your face from dialing the phone is broken, battery life is in the toilet again, and the new OS is crashing.
