well, it comes with a kinda snazzt little slip cover that I still use, but I am used to having my bulky wing on my belt...that is what I prefer...so I am thinking about going back to that...
but as far as cases, T-Mobile really hasn't had any any time I went in...but check Amazon...they have PAGES of cases/covers/misc protective doo-dads for it...some that look fun to me are the covers/skins or w/e that have a matching wallpaper...
In fact,
Here is the exact OEM case it comes with
and it also comes with a screen protector ON it from the factory...it has a little tab to pull it off easier if you dont want it...this tab is perforated. I just removed the tab and my screen is still 100% unscratched... my brother got his phone at the same time as I did, and I believe he removed the entire protector, and doesn't use the slip case, and his is scratched to hell already...we got them the DAY they launched...lol. so, yes it will scratch easy enough if it is not cared for...but with just a little care, it looks great.
I have shown it to all my friends, and they all love the phone also...it has a ton of fun apps. and even my non tech savvy friends like the phone. my tech savvy friends like it even more, cause you can SSH and all from it.
I would say right now, the only things that come to mind as bothersome is the filesystem is I guess read only? you can't browse the phone out of the box, and the browser app doesnt have support for anything, you can see there is a jpg in a folder, but cant open it through the app...and the other is that you have a task manager, but it wont let you kill stuff...if an app freezes, it will ask you if you want to force close, but you cant go to the task manager and just say force close browser for no reason...
as I said earlier, there ARE problems with the phone, but nothing that has gotten me so bad it really bothered me, just kind of slight disappointment, but that is the other thing...the phone is Open-Source, so SOMEONE will probably get all these things I said fixed...just a matter of time as I see it...
WOW!!! I just realized how much I typed...lol
