You would think that an Android phone like the Samsung Replenish wouldn't draw much attention from independent Android developers, but you would be wrong. Android Central ROM developer Shabbypenguin and his cohorts in the ACS have cranked out the beta version of LeafROM for the little eco-friendly Sprint qwerty phone and it already has a great set of features in place. Besides being theme-friendly and debloated, things like the Gingerbread malware patch have been added, and things like "rescue server" (regarded as a carrier tracking app) have been removed. If you picked up a Replenish, and want to have the Android experience of rooting and hacking away at it, you need to have a look.
