There was a thread on this and another BB forum that asked what the essential apps on a BlackBerry are...and I had to post that the BBSmart Viewer was the one app that I simpy refuse to do without on a BlackBerry.
I purchased the program while on my 8300 Curve...and couldn't wait a day until I had PM'd Neil to request another activation code so that I could use it on my new 8310. I am probably going to get an 8820 also very soon...so I'm sure I'll be firing off another PM for yet another code for that one also.
Although I am a huge BlackBerry fan...I am not a fan at all of how the emails are stripped and displayed. The BBSmart Viewer enhances the HTML emails so that they are clear and readable...and it rocks!! A "must have".
