NCKAer iPhone Users - How good is it?

I still wont be taking my phone near the water but here is a link to a waterproof armband that you can put the iPhone into.

I had one for 3 weeks and returned it due to many dropped calls. ATT begged me to keep it and said there were many new towers coming on line soon...I can't believe they released this device with the connectivity issues. I have a sales business and cover from Redding to Fresno and out of 20 plus calls a day, 4-5 would drop. Frustrating. And trying to read emails or view a website (even with reading glasses) is a joke. I use Sprint and have been happy with call quality and plan (check out their SERO plan...available online only for killer deals). Anyway, I'm using my laptop on the road and getting along just fine. I think most buyers of PDA's are not impressed with the iphone and see no reason to move from their blackberrys. The Att dropped calls are getting to be a real  PR problem for ATT and Apple with both sides pointing fingers at each other.
Your mileage may vary.
