in discussion with several carriers about a takeover, it said. Amp'd did not comment. Amp'd filed for Chapter 11 bankruptcy in June to the U.S. Bankruptcy Court in Wilmington, Del. At the time of filing, the company was more than $100 million in debt and owed $41 million in network use fees to Verizon Wireless, which created Amp'd in a joint venture with Vodafone. Amp'd has since added more than $15.6 million to its Verizon debt. Last Tuesday, Verizon asked the Wilmington court to let it cut off service to Amp'd, which it said had failed to secure “debtor-in-possession” financing. The judge set Monday for a hearing, which a Verizon spokeswoman said was still in progress at our deadline. Amp'd customers must still pay their outstanding bills, the company said on its Web site. “Failure to pay a delinquent balance may result in reporting to a credit agency,” the company said on its Web site. Customers awaiting a rebate, refund or other unpaid credit must file a claim, it said. There will be no termination fee owed to move to another carrier, and purchased Amp'd songs, ringtones and videos will still be accessible on the customer’s memory card, it said. Amp'd was still advertising its plans and phones on its Web site Monday. A link to the end-of-business notice labeled “Amp'd Customer Q&A” appeared at the bottom of the page.
