If it's as good as the Z600 then I endorse it as an excellent replacement..
10 December 2011
Summary: The truth is that I haven't used the phone yet! I bought it as a replacement for an old SE Z600 that my wife thought was great. The Z610i seemed like a perfect update and my wife is looking forward to using it. It is for overseas use and that's the reason for the inactivity. If it's as good as the Z600 then I see no reason for not endorsing it as an excellent replacement.
Summary: I like the looks, and it's been a hard cell phone to learn it's features but when you are having a conversation you can't hear a thing. Then you lose your connection with the other person. Then you have to call them back. I haven't been able to even use the phone to talk to anybody.
