I have a E71 and I consider that the software is kind of difficult to connect to, is very slow compared to for example Nimbuzz and my phone gets very slow when i use Nokia messaging. Besides, when I want to sign out, It takes like for ever for my phone before I can do any other task. In reference to Messenger, I cannot arrange my contacts the way I want to. I would like to have the option to see the online contacts altogether. Also, I have had to reboot my phone a couple of times while using Nokia messaging because my phone simply stops working.
I think it is a great idea that Nokia releases it own community service, however I consider that It has to be improved a lot.
