Hi guys. Had my iPhone 5 since launch day. Last 3 days i have had a significant amount of 'call failed' calls. Usually happens between the 3-10 minute period of a call. It was bearable until today it hung up on a phone interview i had for a job. Do i have a defective iPhone or is this happening to others? Info: - Provider: Telstra (highest performing Australian network) - Connection at time of hang ups: Full 3G or 4-5 bars LTE - Model: iPhone 5 Black 32GB Thanks a lot oh and i'm not 'holding it wrong'
