[XPERIA X10 General] epinion:
I would like to share about stock Social Phonebook on the new 2.1 update.

This is what I found so far. And please share what you found too.

As far we know Social Phonebook will automatically Join our contacts from Facebook, Twitter, Gmail, Yahoo Messenger, Spotify, etc.

I. Facebook Integration

The most annoying one is when it change my phonebook name with the name from facebook. This is what I found about it.

1. SP (Social Phonebook) will automatically join contact from phonebook when it has the same name (first and last) or phone number or email. And it will show us the name from facebook.

2. If we join manually and our phonebook first name has the same name as the facebook first name, it will show you the name from the facebook. Example: phonebook name John, facebook name John Doe, it will show as John Doe.

3. If we join manually and have different first name from phonebook and different name from facebook, it will show us the name from phonebook. Example : phonebook name JOE, facebook name John Doe, it will show as JOE.

II. Yahoo Messenger, PingChat, and ... (haven't try more than that) Integration

Our new SP is a more complicated than the last phonebook. It has a lot more feature. It can even integrate with YM, PingChat and I assume a lot more.

1. If you put Yahoo IM in your phonebook and have YM official app at the same time. It will integrate seamlessly. Everytime you click your contact YM it will automatically in the chat mode at your YM app. You can even directly sms your contacts from YM app (if the phone number is support by YM). And if you choose Contacts Detail at YM it will show you whats in your phonebook contact accordingly including FB status from your contacts.

2. If you are using PingChat, you can link using PingChat app, or add it manually via phonebook. To add from PingChat app you could click link contact inside of the app. To add from phonebook you could add field->IM->Custom and type in PingChat insie the Custom Field Name and type in your friend PingChat ID for example : onetwothree (PingChat) <<== yes type (PingChat) too.

III. Powerful Contacts Avatar/Pic.

At the left side of your contacts name inside the phonebook lies your contacts avatar/pic. If you click the avatar, it will show you various pop up menu (most basic one is Dialer, Phonebook, and Messanging).

1. If you join your contacts with facebook it will show you facebook icon and when you click it, it will call FB official apps. (I guess this also applied with other join contacts? )

2. If you have either IM (mine is YM and PingChat), it will show you one of the icon whether it's YM or PingChat. When you click it, you can choose between the app and it will directly call the in the chat mode.

3. If you have address, it will show you Google maps icon too. When you click it of course it will show you the map location. ^_^

4. If you have email (I'm using K-9 Mail) it will show you K-9 mail and when you click it, it will bring the app in the send mode. (I'm using K-9 mail and Handcent, with the stock messanging and email the icon it's the same so rather confusing).

Will post more if I found anything else. Please share yours too. ^_^ .

Still have a Blurry Contacts Pic in call though (even using Timescape method <== thanks to tigermrk for mention it).
