The 7270 trick would also ask you for the security code, just remembered of that! Well, you can go to options and ask to Reset to Defaults (thats what the 7270 key does), but it will also ask you for the Security Code. There is a way of making a Hard Reset. In the Restoure Defaults, the telephone goes to the ROM and loads everything. On the Hard Reset, it flashes the ROM and then gets the information of default. The reason im telling you this, is because Hard Reset doesnt require the security code (?), therefor you would be able to restore everything. Try Google, cause I no longer remember on how to do it.
