Hey did you know you can donate your old cell phone's to us? We don't sell them we have a barrel in our store from a local all volunteer org. called Secure the Call that picks them up. Reprograms them for 911 use and then in turn gives them back to folks that need them like, victim witness, LAWS,dept of aging, etc. check them out. I use them because I saw the same barrel in the Loudoun County Sheriff's office in Leesburg. It's still a donation and you can still get a reciept. What they can't use or reprogram them dispose of properly.
Check them out at http://www.securethecall.org/.
Their website has a FAQ page. It will answer all your questions. Main thing is, if you no longer are using the phone, switch the service to you new phone or have it discontinued.
