"For a long time I have been searching for a portable device where I can store all of my CDs in MP3 format and stream the songs wirelessly to my HiFi system. The portable device must I've tried FM transmitters, they all suck. I don't want a docking station. Any help? Thanks!" have a display so that I easily can scroll through the playlists (I don't want to use a TV or monitor). I suppose that there must also be a second device that is connected to the HiFi system that would receive the wireless streams from the portable device.
So why are iphone's not used by the government? Oh that's right because the security is so weak and can be jailbroken easily. When activated on a BES and a password set on the device it is not crackable, 10 wrong attempts at the password will force the device to wipe. Not even RIM engineers can crack it because it's that secure.
Yes it is slightly bigger then the iphone, but dont judge something until you have had one in your hand and used it. And before you say yes I have used both.
