I don't know what eraser you're talking about, but the claendar-button sets the purchase date to the release date. Of course, if can't do that if the release date isn't listed in the profile...

Quoting Touti:

The "Erase" is the one just on the left of the calender, you click and it erases the date, to me it makes it an erase 

Edit:  Now I clicked on the one just under the erase and my PDA is completely hung, I can't even turn it off.

2nd Edit: OUps, I clicked the Quote instead of the Edit
