I just accessed the page on my phone (SP5m) using the link from Smeg's post above and it downloaded and installed the cab file without any problems (didn't even have to power cycle the phone). I already had 9 options on my menu too. Now there is an option "0" to "Mark All as Read" and the last option is not numbered. It just says "Delete All". Cool! Those will come in handy!!
However, I did the same thing on my 220 and it didn't work. Those two options are not on the menu, which is 9 options long just like kid's.
