The Internet-based transition was further marked in 2005 with the on-air, Keith Urban ringtones review of "SmashTheTones" (now "Mobile17"), the first third-party solution to allow ring tone creation on a webpage without requiring downloadable software or a digital audio editor.Al Green ringtones claimed that Cingular billed its customers for Jamster! and other similar ring tone services without providing customers with the notice, opt-in, and proof of authorization requirements necessary for such charges.The devices are very popular with some businesses, where they are primarily used to provide N.E.R.D. ringtones access to roaming employees.
