to keep your accounts separate, use gmail's labeling system. they'll still show up in your inbox, but each email message that has a label, will show as such. i have my hotmail accounts being checked through gmail and are labeled with their each of their respective email address, so it's clear which account is which.Same issue here. Hotmail and live accounts set up and I got mail regularly. Then it came sporadic and finally nothing. Verizon gave me a new Droid, after their tester phone got my mail and mine did not!
I have now set up my Gmail account to accept/forward my msn accounts. I get my mail, on time and all of it, HOWEVER, would love to have my accounts separate!
gmail also creates a folder for each label you define, so they get stored separately in their own folder as well.
