Is anyone having access problems with Nextel Mobile email????

I'm using a i90, and I'm having problems (4 days now...) with
accessing my Nextel mobile emails.  Keeps coming up with this error
message: "Unable to contact your mail server".  Their mobile email
service has been good in the past.

Way back in 08/03, they had the same type of problem....and it was
with one of their mail servers, and it was replaced due to technical
problems and was down most of a week while they were fixing it.  It
was not on our end, but on Nextel's.

I called 11/22 & they could not solve the problem. They referred it
higher up the chain...to their tech's. Nothing at all was said...about
any possible server issues.

I'm waiting patiently for their reply...
