About 5 months after I bought this phone, I couldn't hear anything that was being said to me unless my phone was on speaker. This can only be done after a call is answered. So I called t-mobile, and they replaced the phone with a new v300. Another 4 months later, and I have the same exact problem. Only this time, if I want the phone replaced, I have to pay for it.Now imagine having to conduct all of your phone calls on speakerphone, no matter who you're with.Seriously, don't buy this phone.
