Just got the SE P1i and surprised to see that BB Connect was installed in the system. Goto BIS web client and change the PIN and everything is working.
I have lost faith in Sonyericsson products because of the P990i but this time they seems to do it right. The P1i doesn't hang once since I have it and BB is running prefect. To us Mac user, Sony even have a plug-in to let the P1i iSync with OSX.

I change all my BB operation from BB 8800 to the P1i now It is not just because of the BB Connect.The most important is because I can now use my Mac to sync all my iCal and address book to my phone and not like the BB device that give us Mac user all sorts of trouble.
