Is there a quick and easy way to clear all entries out of the calendar? Also for some reason I cannot delete messages in the Inbox. Is there a way to clear the Inbox as well?

Thanks.

The easiest and quickest by far is a simple hard reset along with making a backup using Ipaq Backup (Sprite Backup) - using the advanced features. You can then run the backup and restore everything but the PIM data.

My "My PDA" now updated with hints and tips including a ROM fix for the RX3700 series and installing Transport Tycoon onto your PDA.

If you're using Pocket Informant, then click on the round coloured symbol (in the bottom bar), select Utilities..., then select the appropriate delete option.

What about if I want to bring them back after updating the ROM image using the same version of Windows?

If you have Outlook on your PC and it was sync'd before the update, then when you reestablish your activesync connection and sync with the PC your PIM data will be restored.
