Time 4 a new phone

[solo ieri]

I have the LG VX6100 & it's time to update. I've been looking at & getting the information on these phones:

LG enV
Samsung SCH-A990
Samsung SCH-U540
Samsung SCH-U740

All look really good to me (physically & on paper) but I want to know a few things the tech sheets don't tell:

How durable is it (say from a fall to the cement)?
How good is the quality during phone calls (with & without speaker phone)?
How good is the Bluetooth (& which earpiece works well)?
How good is the sound from MP3's?
Can I listen to music & take a phone call w/the same earpiece?
Does it work w/Bitpim to transfer pics & music? If not, what software works well?

Though not very important, is there a way to remove the clock from either screens on the LG enV as the other phones can do?

Look in the verizon phone forums for info on these phones and reviews plenty of info on them there.
