I bought Nokia N70 nearly 2 years ago. I went to the shop and the guy was suggesting that it is the best product between Sony W810 and N70. I bought N70 because of its looks. But after some time I found it is very slow and some time hangs.
There no mention of the key board lock but it works same way as other Nokia phones.
It is only tri band(900/1800/1900) so when you visit US you can not receive all calls. Especially in large buildings and you are in the center of the building.
If you want to take picture you need to wait for some time after opening shutter.
The battery capacity reduces as the time goes by. Now I need to charge every day to have enough power till the evening.
The option for Speaker phone is confusing when you are on Mute.
