That would explain it, except that it's working perfectly for some and not at all for others. There's more at work here than meets the eye. I did find the following thread on the Apple Support Communities forum:

Well yeah, iCloud isn't just one server, I'm sure there are many, just like gmail, msn, yahoo, and any other email service.
Think of it this way. Has anyone used a blackberry before? Well you have to sign up for BIS (blackberry Internet service) and pay extra to use it, without BIS servers, no blackberry would ever retrieve their mail. Apple use to charge for a membership (aka server space) on MobileMe, which can kinda be looked together as one in the same, BB never has problems with their server, cuz, for one, they been doing for so log, and two, they don't get very many subscriptions to BIS as apple does, so they hardly have problems even if their servers die all the time.
BIS checks for you email in this way:
BIS checks for mail in 5 cycles of 3 mintues (equaling the 15 minute cylcle) then it goes back to 15 minute cycle. For example:
BIS checks the account when it is set up.
BIS doesnt find email.
BIS checks back in 15 minutes.
BIS finds email.
BIS compresses and sends email to the handheld. (first 2kb of the email)
BIS checks back for mail in 3 minutes.
BIS doesnt find mail.
BIS checks back for mail in 3 minutes.

and so on and so forth.
this is not for gmail/yahoo/carrier.blackberry.net accounts
With these accounts there should be little to no delay from receiving the email to the notification on your device. BIS checks continously on gmail and yahoo, and since there is no mailbox for the carrier.blackberry.net account (the device is the mailbox) it is instant.
Anyway, this isn't about BB or BIS but it was a 'for example'.
In apple server room is hundreds of servers that help us all get our mail, fair enough to say, right? And if it wasn't for those servers, none of us would get mail on our iphone, right? Servers die all the time, and its safe to say some may experience a lil difficulty retrieving mail cuz if 1 server dies, and it was hosting (for example) 10,000 people's email accounts, those other servers have to compensate and work just a lil bit harder to retrieve mail, and push it to your iPhone. Without apples servers, mail wouldn't be possible on your iPhone through a native app.
It's fair to say, that the servers are a bit over ran ATM, and some of us are experiencing some issues.
Sorry I cant explain it better, but I just dont know how without writing a book. :-/
