The Contacts system on the Sony Ericsson Xperia Mini Pro is precisely the same as the one seen in the Xperia Mini, with Sony Ericsson giving it a simple text interface and adding some ingenious Facebook integration.
As well as importing all of your Facebook chums when or if you sign in with a Facebook account, the phone also adds an entirely separate Facebook page to the Contact data. From here you're able to browse other people's Facebook info and interest pages, and their photos also pop up.
If you're not into all that social networking business you don't have to use it. And if you'd rather not see your internet acquaintances staring out at you, there's the option to filter the Contacts section to stop Facebook people showing at all.
In terms of fiddly fun stuff, you're able to allocate separate ringtones for each contact from the Edit Contact page and send people you hate straight to voicemail. Plus there are fields for instant messaging details, websites and an internet call option for using the emerging SIP Wi-Fi calling features.
The Sony Ericsson Xperia Mini Pro's regular old dialler is a simple option, with shortcuts for your call log, Contacts and Favourites along the bottom.
There's also a useful Save button that automatically pops up with the Contacts list if you'd like to associate the number you've just dialled with an existing friend, or to add a new person to your phonebook.
The on-screen numeric keypad disappears if you pull out the QWERTY keyboard, as the Android smartphone assumes you'll want to press the physical buttons if you're using it that way.
Call quality on the Sony Ericsson Xperia Mini Pro is every bit as good at it was on the standard Xperia Mini. The speaker is exceptionally loud and really sharp. We got through calls with its volume set to less than half its maximum, so there's absolutely no chance of this one being thought of as too quiet.
In hands-free mode, the Sony Ericsson Xperia Mini Pro is also one of the loudest phones around. Calls and media blast out impressively noisily.
