Has anyone found a spring clip holster that works with either Amzers 2800 mah battery & back cover or Seidio's 2600 mah? Seidio's website says they have an innocase for their extended battery "coming soon" for several weeks now (maybe "coming sometime" is what they mean) and I assume a spring clip holster will follow. Trying to wait for a touchstone back for these batteries & a spring clip holster but it's starting to look like it's not happening.
