I want to get an arm band and case so that I can use my droid for my workout. I am sure others will eventually want to do this same, so use this thread to talk about those types of cases. I really like arm bands that don't need me to take my phone out of the silicone case.
I know one that doesn't work already. I bought the Arkon Sports Armband (for large smartphones) on Amazon. It's not tall enough for the phone. It definitely doesn't fit with my silicone case on the Razr. Without the Razr the case barely fits....you really have to work the phone into it. The touch screen works through the plastic cover, but the cover is not tight to the phone's screen, so it's still difficult to operate the phone.
I'm going to try the Amphipod Armpod. Bionic owners in the forum swore by this working well with their phones. I'll report back in a week or two about how well it does with the Razr.
