For those coming from WM, you may remember the "mark all read" cab that was real handy. If you're a ROM flashing junkie AND are stuck w/ only POP3 AND have multiple accounts, you'll appreciate this.
Previously I had IMAP accounts, so this was not needed, but I have recently switched ISP's and am stuck w/ POP3. After flashing & adding my accounts, I usually have hundreds of new emails, so the mail icon shows the infamous 99+. After searching, I FINALLY found a solution!

I'm gonna leave this thread here for a couple days, then moved it to Android general forum.....
