I got the 8900 and so far, I must say, I am not overly impressed.
To me it seems like a streamlined curve, with nothing much more to offer than it's nice display and semi-upgraded browser.
My particular dismay comes in the for of the GPS operation. I have tried Blackberry Maps, Google maps and amAzegps. They dont find the satellites. If this problem continues, I am going to have to send the phone back. Are there any settings that I might not be aware of that need to be enabled in order for the tracking to be allowed?
