DO NOT INSTALL THE UPDATE! You will not be able to access the set up for your email accounts. You will get major latency too.
Also, when you attempt to exit the set up feature, the phone will lock up and you must re-power to exit.
If you call technical support they will want to configure the email accounts on some BlackBerry web page, but that will not solve the problem of using the set up features for your email accounts.
The software upgrade is a major QC/QA blunder for RIM.
