Found: mobile phone, in marsh grass* above Lower Chelburn Reservoir, between the Pennine way and the town of Summit (nr Rochdale, on the A6033), on Sunday 13th July 2008.
After finding no advice on the relevant phone company site, I managed to make my way through the phone system to report it missing this morning.
I have no charger for this model to power it up and check for details, however the mobile firm will be sending a freepost bag for me to send it back to them. The phone seems to have been lost rather than stolen and abandoned, as it still had its SIM and extra memory in tact. Some water damage by the looks of it.
*Incidentally, marsh grass and Terrocs don't work, but yes, Terrocs do drain quickly and yes, I hate wet feet!
