I am curious in regards to the Motorola armband. I have been using my Zune case (Original 30GB Zune) and the Epic fits snugly, but while running sometimes it seems like my GPS loses signal (Stock EB13) and when I look at the route on runkeeper it looks like I am running through houses. With the Motorola armband or even the Arkon, has anyone had any issues with the GPS jumping them on their route?
The last time I ran, Runkeeper told me I ran only 1.75 miles when it was actually 2 miles. The 1/4 mile may not seem like much, but when tracking personal stats, it is a pretty big difference.
