I've had good luck with my seal-line e-case, the zip top one. its been pretty durable, I keep my phone in it at work, and have been doing so for over a year now. Another option is the seal-line (or they might be hummingbird brand now) see-pouches, its a roll top with a clear vinyl panel. They should work, a bit more bulky, but a simpler closure.
Ortlieb makes some much cheaper and lighter splash proof soft cases for phones as well, they are a roller with velcro closure. Just depends on what you need as far as rugged and waterproof, as there is a range. The ortleib stuff should be available at cycle shops.
