When I got the phone, within a week I purchased a 1GB SD card and loaded it with MP3s and took it to work with me. Was I ever dissapointed in the way the built in MP3 player worked, so much that I never used it as an MP3 player after that first time. I hated that the phone would lock after so long and the only buttons that would work with it locked were the volume controls. There was no way to pause a song if someone came up to talk to me without unlocking the phone first. It did allow playlist creation.
dont like the built in player? download another one, get one that you like theres litterally THOUSANDS of mp3 players for pdas, with the iphone you dont have that choice. you can even play XviD, DivX, well any format you can think of you can play on a phone thanks to 3rd party.
The iPhone does allow us to pause the music by pressing the button on the headphones and it also allows the volume to be changed by using the buttons on the side, all without unlocking the display.
yeah all WM phones does that too and im pretty sure your treo can be setup to do that (well X-Treo?)
My iPhone also took all my contacts from Outlook that had automatically been synced the last time I used the hotsync on the Treo. It also loaded up my email address. The only change I had to make was to remove the password from the outgoing because it's not needed and caused the email sending to fail on the phone.
it may have sync'd basic things like name, number, address, etc but it missed all the other fields, the iphone sync is completly crippled as the phone itself doesnt support alot of fields at all.
