Can't recommend this if you are using N97. This software worked perfectly on the E71 - on the N97 it appears bug ridden.
There is no visual mail received symbol (@) on the home screen, or pulsing notification light, so no way of knowing if you have received an email when in silent mode.
Touch screen is not as responsive as other applications, this makes the application hard to use in "portrait" mode.
Finally, the interface for some reason is clunkier, opening the application goes straight to an "inbox" rather than a screen where you can select, mailbox, settings, sync, etc. - sync has for some reason not been ported to the N97, you have to dig down and do a "send/receive".
I thought this application was one of the best on my previous Nokia - hopefully these issues are addressed soon.
In its current form this application is little better, if at all, than the standard mail app included on S60 devices.
