This is a great phone+PDA.Phone alone, not so great because it is very sensitive, can't be rough with it.It is Windows Mobile 5, so it crashes :(, I read that AT&T; will offer a free upgrade to WM6Battery life is short.But I love it, it is great having a PDA as a cellphone. You have got to get the Unlimited Data Plan from AT&T; for $40. I installed OctoTalk that allows me to use MSN, Yahoo, AIM, and ICQ messengers and stay connected. I downloaded Skype so I can call for free. All the time connected to my company's Exchange Server.I bought this phone less than a month ago and I am very happy with it. But you can't treat it like a regular phone and be rough with it, need to be gentle ;)Update:After using this cellphone for some time now, I will not recommend it to anyone.Windows Mobile 5 crashes a lot, AT&T; offered WM6 update, but it still crashes. The battery life is less than 8 hours on standby.I am changing this phone...
