My Reqwireless on my BlackberryOS 18.104.22.168 with my Mailstreet BES/MDS. It seems to have problems if I don't have MDS.
My Reqwireless has no such error but I am unable to get it registered properly, because when I try to reregister it with my current key from my email, http://www.reqwireless.com/keyex.html
... it gives me an error message that my Version 3.5 is no longer supported.
I manually went to http://www.reqwireless.com/keyex.html
manually in Internet Explorer and did the exchange there, that succeeded, and I was able to get my Reqwireless reregistered. But damn, I've done the key exchange about 8 times in the last few months because of reinstalls and OS upgrades. (Can't they make the key exchange rerecognize any past key, rather than just the most recent key?)
Reqwireless is still faster than the Blackberry browser, so I like to use Reqwireless. It downloads http://news.google.com
more than double the speed of Blackberry Browser.
