Downloaded and installed 3.1 everything went smooth. Installed 5.1 carrier file, MMS is working wonderful. But not my mobile me email isnt being pushed. I deleted and re-added. Also looked under settings->general->network->cellular data and the APN is wap.cingular but username and password are blank. Dont know if that has anything to do with it. Internet is working and emails will come through upon opening mail. Yes I DO have push enabled. Any ideas? Thanks guys/gals.
