New to forum, Yahoo email help

[slopike]

I am new to the board. I have been a basic iPhone user for 3 yrs, my wife has one and my daughter has the iTouch. THings are prettty smoot, but I jail broke my phone with the help of an IT guy and soon after my yahoo email stopped working, saying my id or password are wrong or password not entered.....nothing I do seems to fix it. I went back to teh normal OS as I didn;t really get much value from jailbreak and am not technically saavy enough to deal with it...if anyone has insights on how I can get my yahoo email to work again, I woul dlove it
