arcsoft is better because it fully integrates into windows mobile, instead of showing up as some weird what looks like web based email account. the default sprint picmail is slow, barely works, and annoying, at best. arcsoft does everything better... if you're in a message, and want to add a pic, you hit menu, insert pic. brings up a dialog, go to your pics folder, click it, click send, and done. i had so many problems with picmail, and arcsoft cured them all. its actually usable for me. i've been mad at sprint for years for not having true mms, and this is as close as it gets.
