Any suggestions for who might be willing to do this? Are you volunteering?
A nice leather pouch might do the trick as opposed to an actual fitted case. I am using a Krusell leather pouch, large size, for my Rumor Touch and I am very pleased with it:
95216-C5, Krusell LUNA Pouch, Blue $16.00, Best Cell Phone Accessories I just carry it in my pocket. I have never dropped the phone so don't know what sort of protection it would provide but the pouch is very well made and I have no scratches on the phone and it keeps the dust and lint off of the phone, too. If we can get the exact dimensions of the LG Optimus with the larger battery something like that pouch might work.
Of course, I don't even have the stock phone yet so this is all speculation on my part.
