I don't know if you can really call it custom, but I took an old Speck 1g silicon case and used to have it on my 2g. Only problem I didn't like is it didn't fit correctly and it put pressure on the volume and sleep buttons. So I simply cut out the spaces for the volume and sleep buttons. It's ghetto as **** but it works until I get my Touch Rebel. Anyway, anyone ever too cheap or lazy to go out and get a new case for something so you just made or modified one?
