recently got an boost i450 (unlocked) for use on my nextel account (from my nextel rep). I have not been able to download ringtones correctly. any attempt from boostmobile.com or the phone directly and i get an error saying the "system is busy, try again later". the one download i was able to get from the nextel/sprint site was the wrong ringtone. description is correct, but the ringtone is definitely wrong. any help or suggestions appreciated...
