I have an iPhone 6 (from December 2014) and 2 weeks ago the audio connector stopped working. When I try to plugin in my headphones, the audio jack just pops out; it doesn't stay in. Additionally, a few days ago, the phone started having issues with charging. I've tested on a friend's charging cable and had the same issue, so the issue must be with the phone's Lightning connector. The last few days, I can get it to work after a lot of trying (repeated re-connecting to different USB ports, wiggling the connector, etc.). I got the phone with a 2-year contract with T-Mobile, so it's still under warranty. I can let T-Mobile service it, but before I do that, I'd like to get a prognosis from you guys ^_^. 1. So, if it's a hardware issue, will they be able to fix the affected connectors, or should I be anticipating a full phone replacement? 2. Will they need to access the phone (I'd rather avoid that)? In that case I'd have to delete my private information, just in case. If yes, will I have to provide them with my AppleID password and PIN? 3. Is there anything else I should do in preparation to leaving my phone with them?
