An iPhone gripe

Walt Mossberg zeroes in on one of my iPhone gripes:

Unlike on a BlackBerry or Treo, the iPhone doesn’t allow you to delete whole groups of email en masse by date, or even to select large groups and then delete them en masse. This would be a good feature for Apple to add down the line.

Deleting every email individually is a big pain. I’d even be happy a “delete the whole inbox” button.
