Thanks so much everyone... Here are my other problems

First, it took me like forever to figure out how to install the update Dingo, alright i got it on now finally
Then it had been like overnight the edge with the AC cable on, so i unplugged the AC cable, guess what? everything went blank, so i hurried and plugged it back in again, then the red light kept blinking.. (ok, now it looks stable) and I went to check the battery status, it said 255%.. how come??

Second, zooming was fine before I installed the Dingo update; i could see the zooming icon on the screen and it was working great, though no custom settings. NOW it wasnt there anymore with Dingo, only the zooming button which doesnt do much, only with 3 hits??... I have a lot of pdf picture files and pdf lecture slides from school, I got the edge just for that reading purpose with this great ability... and now.. HELP!!!

Oh, my school wi-fi needs all mobile devices to get first registered their mac address before they can access free wi fi, pls tell where I can find it on my edge?

Thanks and Help me..
