HTML formatted messages are not supported on several BlackBerry Bold devices
Posted by on 22 April 2011 10:07 AM

Several BlackBerry Bold devices run extremely slow when attempting to synchronize HTML formatted email messages.
It is therefore recommended that users of this model disable the HTML option.

From the GO!NotifyLink or GO!NotifySync Preferences menu, select Email Settings.
Under Email Body Type, select the Plain Text option.

This is a device limitation.  Other instances of sluggish behavior on this device model have been observed by users and has been documented in BlackBerry forums.  This has been confirmed on 9650 model devices but affects several others as well.
