Bought Bionic on first day. It freezes from day 1 and needs battery pull at least once a day. Last week, when I was abroad, the headphone jack no longer works. Music still comes from speaker, nothing in headphones. Really love this phone, though. Smooth, fast, and even the interface is reasonable. I need to get new replacement under warranty. Any advice in getting a new replacement? How do I deal with the Verizon store where I purchased it?
