Facebook and blackberry...

Small advice - totally non-cycling-related:
if any of you is using Facebook on the blackberry 8800 and has T-Mobile as service provider - DO NOT upgrade to Facebook 1.6 on the blackberry!!!
According to our enterprise server people all employees that are AT&T customers upgraded fine, but all of us with T-Mobile are having trouble - and most of us lost data (emails, passwords, attachments, etc) in the process. Not sure I understood exactly, but they say T-Mobile smartphones software is not compatible with the new FB version - so if your carrier is T-Mobile just keep your facebook 1.5 and keep your data safe.
I had no clue about this, so when I received the upgrade notice I clicked 'yes' and upgraded - and now my berry is all messed up!!! :eek:
