I had been using this phonefrom last one month and faced no problems as yet. It takes time to get used to the keyboard but there are many options for onscreen keyboards in it which gives ease of use. And with whole lot of applications available on the net its a good phone to use.
If you require Wlan then you can think of some other available options. rest the phone is great. the battery life is around 2-3 days with moderate calls and multimedia usage.
