I have an old Innopocket aluminium hardcase (for a Treo 600) that i've retrofitted (in other words - bent and hammered) to fit my 650. The only problem is that i've worn out the thin rubber liner on the inside of the case. Now, when i slide my Treo in and out, the exposed metal tends to scratch my phone up. Anyone out there know where i might be able to find some really thin rubber liner, like what's in the case now. (The liner has some sort of sticky adhesive on the back of it.) . . . thanks.
