That phone is the ****. I had one for a week, but had some issues with the keypad lights, and wasn't terribly fond of the UI look. It is a powerful phone, and frankly i wished i had it.
But after the 1 time exchange (can't go back now :( ) i've got the Samsung M610.
THe 2megapixel camera is nicer, but no flash or macro mode like on the 8400. It'* definetly taller and wider, but it'* the thinnest flip right now. It has the best screen i've ever seen on a phone, and the UI is superb. The Soft touch rubber outside is also very nice.
But bluetooth range is pretty poor, the speakerphone uses the normal earpiece and mic (can't work when closed) and the microSD slot requires the battery to come out.
I brought it back to get the 8400, but only one exchange
Funny how they never mentioned that nor was it in the sprint stuff I have.
If i lose, break, etc my Samsung, the 8400 will probably show up in my pocket.
What plan do you have? I'm guessing you have powervision services, do you really use them much?
