I went to blackberrys website and downloaded the newest desktop manager 4.3. When i connect my blackberry it's asking me for to "enter key store password
"

What is that? I'm guessing it's something to do with the fact i didn't download it from my carrier's (AT&T) website, but they don't have 4.3 and i LOVE the GUI of 4.3 vs. 4.2.x.x and previous versions.

nevermind....for some strange reason when i plugged it back in it didn't ask for it and everything is good....i have no idea!

but i love the look of 4.3. It actually looks updated and not like it belongs on windows 3.1

Too bad 4.3 is crap and full of bugs.
I'm sure you'll be back to 4.2 in no time!
