Hmmm....here's what I got from the past 20 pages:
GOOGLE MAPS - turn on GPS in the Menu...scroll down <---this is the setting most are missing and why they're constantly searching for a GPS satellite instead of locking on to one in a few seconds.
WALL PAPER ON ALL TABS - mods from 2.0 will not work in 2.1 - ALL of the old wall paper mods will fail. FAIL I SAY! ...there is the slick HDWalls program which some folks are using with the panoramic view wallpaper that seems to work really well [links have been added to the Guide in my sig].
REMOVE CALL HISTORY - again, mods from 2.0 will no longer work, so we're stuck until we start seeing new mods for 2.1. ...this thing [2.1] just came out a couple of weeks ago, give it time.
RETRACTABLE SLIDE BAR - installing this will knock out your default wallpaper on all tabs...in portrait. Just something I noticed. I still like it.
WORLDCARD MOBILE - dude, THANKS...I had an old cab that wasn't working and I thought it was a lost cause...I actually get alot of use out of that program at meetings.
TXT and EMAIL buttons on keyboard - J.eremy's fix totally works. I have "display account picker" selected [because this also seems to stop my inboxes from randomly opening]. When i hit the TXT button it goes to texting. When I hit the envelope button it opens "messaging" and allows me to select which email accoutn I want to send from.
...oh and I'm printing up "flash to stock, hard reset, flash to custom rom, hard reset" shirts if anyones interested.

It's the new up, up, down, down, left, right, left, right, A, B, start.
