Hi all
Well i am also now using the Seven always on E-Mail Beta trial especially as it now supports MSN/Hotmail and am in no way connected to any of the other posters or any resellers of the app.
I first used it on my N95 8GB and am now using it on my E90 and i haven't noticed any slow down of my devcies either.
The thing i like about it is just how easy it is to set up all it requires is to choose the services you want to use and enter your user name and passwords and that's it which is all done on your devcie. It also has plenty of options as for the hours you want it collected between and different settings for workdays and weekends. I like this app so much that once the trial ends i will actually be happy to pay for it.
