My last cell phone decided to fly out of my hands at a high rate of speed directly towards the cement basement wall. Damn phones can be tricky! Now I'm playing with a Sony Ericsson Z50a. I haven't used a flip phone in about 2 years, but it's kinda nice to tinker around with them again. Solid, soild build, too. I've always hated certain flip phones because the hinge always felt like I could snap it in half. But this one, really decent, real solid. Cool features, even though I'll only use about 5% of them. Would of been nice to be able to close the phone with speakerphone on, but oh well. If anybody has this phone, what the hell is the black oval thing on the left side at the bottom, about a centimeter to the left of the charger port?
