It's either a Motorola or a Verizon customization (sucks!)... not an Android thing. The Android 2.3.4 user guide shows on page 223 : http://static.googleusercontent.com...lp/hc/pdfs/mobile/AndroidUsersGuide-2.3.4.pdf shows all the customizations you can do BY ACCOUNT (including unique ringtones by account). Motorola or Verizon has swapped the "combined inbox" and the "all-in-one" view I'm used to for the "universal inbox" (have to check each account) and taken away all the other customizations that can be done by email account. Yep. Definitely don't like it.
