Hi!
Being very disappointed with mobile me losing my emails, not pushing the way it should, ..., I began looking for other alternatives. I think we could put together some other services here.
To start, I found (and am currently using with much success and liking it):
www.interways.net (interWaysMAIL)
I can definitely recommend these guys... BTW, they are way less expensive, complete push is $4.99/month in my plan.
Please add your experiences with them and other alternatives, this might help those looking for better services!
