Today i tried Nokia Messaging IM. It's going good, but need some improvements so it can be perfect:
1) All the Services should be in one tab. Why? Its kinda annoying keep switching between all your services.
2) You should be able to modify message volume. Why? When you get a Message its too loud, at least for me on my Nokia E71 - Windows Live Service.
3) There should be an option to rename your contacts. Why? at least i find this more useful that their own nicknames.
4) More Services support: Skype, Facebook, Twitter, Jabber, ICQ and many others. Why? Everybody use most of them.
5) It should allow you upload your personal avatar for Windows Live Community. Why? I really would like it, i have been looking for this feature and no one offers it.
6) Chatting screen is just kinda small, it should be more bigger. Its kinda awful, since the chat screen is too short so you have to scroll almost everytime to keep an eye in the chat.
7) There should be a pop up notification back in Home Screen. Why? Sometimes we are busy or away from phone, so it will be really nice that it informs us that we got a message.
8) it should be integrated with Contacts tab as Ovi contact does. Why? I really find this more useful.
9) There should be more options, so we can customize this nice program by our own. Example: Hide offline people.
10) It should show avatars (MSN Service). Why? I really enjoy this feature.
11) chat timestamps. Why? Because you need know most time when did you get a message, mostly if you were away from your phone.

You guys are doing a nice job! Hope some of these suggestions come live!. I really enjoy its user-friendly and also its own theme is cool. Its really great, but could be improved with some or all these suggestions i made.

Thanks in advance,
