Some Samsung Intercept owners find their phone in a coma after Froyo upgrade8
The carrier hasn't publicly said what it is going to do about those with bricked units, but Sprint did apologize for the inconvenience while it investigates what happened and corrects the problem as soon as possible.
If you were one of the unlucky Samsung Intercept owners whose phone was bricked by the upgrade, there is an unofficial fix available. The update.zip that is allegedly the same program that Sprint is currently testing as a fix for frozen Samsung Intercepts, is available to install at your own risk by clicking on this link.
