I remember a thread and poll about this a while back.. yes they were loose then and now, as it just so happens that I was swapping batteries the otherday and my screwdriver was handy so it' gave them another snugging up. I do drop that phone ALOT so loose screws is par for the course I guess.
mine weren't supper loose, but they did take a good 1/2~full turn.
I think the only difference is that the next time I drop it the shell will do its job right and protect the screen and insides better.
edit. maybe TEP should send reminders every 6mo's or so to remind ppl to bring it in for a "check-up" kinda like the dentist..
