Hi, I already have the N9, but the following are missing. I hope they will be added back later on:
- The intelligence to recognise a phone number is Mobile and will only enable addressing Text messages to those numbers.
- AIM account plug-in for contact and conversation.
- Yahoo account plug-in for contact and conversation.
- MSN account plug-in for contact and conversation.
- infinite number of Tel phone entries per contact, with the ability to "tag" them as "mobile". "home". "office". "fax", etc. (I believe currently the contact in N9 only take up to 3 tel phones per contact record.

The following is not specific to Contacts/IM but is relevent:
- Ability to increase font size on text.
