I have to say I love this phone - with the exception of a few things which hopefully samsung will release a firmware update to fix:No syncronization with any sort of PIM at all - not with bluetooth or the provided but useless USB cable which is used to "tether" the phone to a laptop for use as a modemNo way of reading wallpapers/screensavers/ringtones/games and assigning them or installing them from provided transflash card - or any transflash card.The only way to add such things is to download them from the provider's site - Sprint in my case - for a fee or find an online service to send the files, which is a pain and sometimes still doesn't quite work.I'm used to being able to add things like that almost on a whim, being a former Nextel phone user and modder but despite the drawbacks above I have to reccommend this phone to anyone looking for a really good phone to use for Sprint service. The MP3 player is excellent quality and is really limited only as how many transflash cards one uses and how much each card holds. If Samsung or Sprint fixes the above issues I'd be more than willing to give this phone 5 stars
