I've never seen the theme in question but I do know that anything even remotely resembling an Apple icon will get you sued. Hell, using "i' in front of any word or a rectangle with rounded corners will get you sued. Hopefully these guys are back on the Google Play store soon.
After hitting 1 million downloads in less than four months a few weeks ago, Themer was suspended from the Play store on the night of February 2nd due to a copyright concern regarding our "Seven" theme (which is just one of over 200 themes available in Themer). Apple Inc. claimed that several icons used in Seven infringed their copyrights.
