I’m sure the avid CM7 user is well aware of the built in theme engine, which allows for scenery changes on a whim. Simply download an apk for the theme you want, install it, and then select it in the theme manager, the process couldn’t be easier. The only catch to the whole process is locating and choosing a theme as there are many available at this point.
Normally finding a theme would require browsing of either the Android market or the Android theme section on XDA forums. If you happen to choose the XDA option you’ll notice a newer post on the first from XDA member mohitrocks. He has compiled a list of quite a few of the readily available, flashable CM7 themes.
The list is a work in progress and will continue to be as themes are released quite frequently. Although the list may not contain every single theme out there for this theme engine it may contain a few you may want to try out. Kudos for this guy for doing the leg work, and making it easier for people to locate the theme that best suits them without having to search for hours. Keep checking the XDA thread for updates.
