Hello,

I would like to answer some of the questions posted, and make some additional comments.

1. If we are comparing E50 vs. E51, besides the better E51 performance, E51 supports BB Connect 4.0 client vs. BB Connect 2.1 supported by E50. Connect 4.0 is packed with additional features aimed at enterprise account activation including:
Contact sync
Attachment viewing
Create/Send/Accept meeting request
Remote Address Lookup
Folder redirection
Filters/Out of Office/Signature all settable from device
OTA Enterprise activation
Wireless Calendar bulk load
Various IT Policies supported

2. When prompted for "Enterprise Activation", say "No" for BIS account, then go to your carrier's web site where you enter device PIN number, your BIS email address and password. You'll find PIN number in BBC Settings once you install the client.

3. OTA reconciliation: Only "Server wins" conflict supported. Email message read/unread flags supported, as well as delete message on device. Email messages going directly to personal folders created on server are all redirected to Blackberry mailbox on device, however folder management is not supported, as Symbian does not currently support folder nesting. Send messages from device are synced to server as well, if configured in BBC settings.

Hope this help,

Rob
