Only thing I can remember right now is muwap.us .But I think they charge you to download from your comp. and not the phone (Stupid kinda).Ill come back with some more.
Go on eBay. You can get a Data Cable (usually a package including mobile charger or something else) and one of the NEXTEL software CDs. Thats what I did. CD literally pays for itself in minutes.
