Customer service can no longer renew contracts for Cellone. A former Cellone retail store can up to a certain date in May. Sorry I don't remember the exact date.

If you use the phone as a modem it will bill seperately than your normal BB data usage, and it bills alot. Once the billing conversion happens, I don't know if it will work at all.

For the last question, if a retail store has any they may sell you one. Customer service can only send things out in extreme circumstances and get hassled about it.
