As far as the memory of emails etc. on a cellphone, blackberry
themselves., I would think they work the same way computers do since
they both use operating systems. Nothing is permanently gone until the
memory address it occupies is actually overwritten... when you delete,
the memory space is just tagged as being available and someone
knowledgeable could have a look at what is still sitting there in such a
state and restore it for viewing purposes.
That said, I would imagine the emails etc are probably stored in .dat
type file structures rather than individual files so another level of
knowledge / complexity would be involved in reading them.
I would think it comes down to being all a matter of resource
expertise and commitment. The FBI or homeland security etc. would have
both. They could go granular on your device and they would have the
authority and the manpower to find and recover email server backups from
server devices anywhere along the email's bounce delivery trail.
Someone said there is theoretically a minimum of four locations that all
emails are copied to.... and might be retrievable from.

In the last few days we have been seeing media reports about
"permanently" deleted emails. On Friday Information Week ran a story that
said deleted emails were particularly difficult to recover from cell
phones and Blackberries.
But I think I remember a raft of stories from last summer about emails
deleted from cell phones and Blackberries being easy to recover. We were
being cautioned about selling our old cell phones on eBay because someone
with just a little knowledge could retrieve all our deleted emails. They
even said that the "delete everything" function didn't really delete
anything, it just hid it.
So which is it? Anybody know?
