Battery meter and Today Screen

[CaptHockey93]

Hey guys. So my Treo reset itself the other day and now I have the volume meter instead of my battery meter. How do I get that back? It had the meter when I first got it, but now it's gone. Also, how do you update your current version of software thru sprint. I have low reception since the reset and now pic mail doesn't work, which it did before. Lastly, what's the best free ware for the today screen (weather, menus, running programs). Thanks and any help would be appreciated.
