bof, I contacted RIM by mail and the answer was: "your SRP key is expired..."
good news!!! :(
I didn't expect that. (the BES is a second hand buy)
so the first user certainly used the SRP key. (bad boy)
no matter RIM redirected me to a dowloading link of the latest BES 4.1v trial version . which works perfectly. (good boys)
but my handheld doesn't work? humm called my wireless carrier. and discovered that they still didn't activated the GPRS connection on my H/H
(bad boys too)
they finally did after my request.
in fact I stressed for nothing b/c all these problems aren't in my responsability.
however some business days lost. :S
