How to know if my android phone is rooted or not?

[Denverguy]

I'm a newbie to the android phones ,I got the samsung vibrant for tmobile last month ,i downloaded an app from the market which is one click lag fix(RyanZA's) ..and accidentally tapped a button which says: root your phone it took few seconds and said that my phone is rooted.......Is that possible ?

Is there anything that i can do to know if my phone is really booted or not?

i looked at the history here in this foroum and found a similiar post i ,so i downloaded the titanium back as what was said in there and upon opening it an Error message comes up :
"sorry,I could not acquire root privileges .this application will*not*work!please verify that your ROM is rooted and includes busybox and try again "

does that mean my phone is not rooted?
should I still expect to recieve the update from tmobile in november?cause this is what i'm concerned about !

Your phone is not rooted. Would be pretty hard to accidentally root your phone.

open up your one click lag fix.. is the option to unroot your phone in green text? if it is, then you are rooted. if the option to root your phone is green, then you are not rooted.

Even if he hit the root phone button he would have to reboot into recovery and hit reinstall packages, amiright? Would be pretty hard to do that accidentally.

the unroot option is red,and if i tapped "force anyway"it would say unroot error:nill

I would hit the root button, let it finish, then reboot, then go back in and see what is there. If you dont want the root then select unroot

i thought of that but upon reviewing the comments on the app ..people said that everything is ok with it except the unrooting which doesnt work right..
so i didnt want to risk that .as i dont want to root my phone .
and would rather wait for the software update in november
any other idea ?

Only other idea is to Odin back to stock. But I doubt you want to go that route if you are too chicken to let your phone be rooted.
