Send/Receive not working after ROM update

[StormRider500]

BlackSpidey- I have the exact same problem. Did you ever get it solved?

I installed the 3.16 rom to my sprint mogul, everything went perfectly. I haven't had a chance to see if the rev-a is faster but the gps works perfectly. I'm able to make outgoing;/incoming calls and internet works fine. One small problem..., I can get my gmail emails but I can't get my yahoo emails. I am able to add the yahoo account information and the mogul says it's logging on, and retrieving messages then I get an error that says unable to connect/verify account is correct and message says ERROR SYNCHRONIZING. Sometimes a few minutes later it will also ask for incoming email password. I also turned on my wi-fi and was able to get my yahoo email messages.... this only happens when I'm using Sprint internet on my mogul. It does not happen with gmail.... seems to be isolated only to Yahoo mail. Also I even went back and deleted the account, reset it up, all correct passwords & it still won't work.
Everything works except this. Has anyone else experienced this issue? If so, any help would be truly appreciated in resolving.
