Verizon released the DROID RAZR MAXX on Thursday for $299.99 with a new two-year agreement. The device features a massive 3,300 mAh battery and a slightly thicker frame than its predecessor, the DROID RAZR. Other than that, the handsets are identical. Droid-Life confirmed on Friday that both devices run the same exact software, in fact — the Android version on both devices features the same build number, same kernel and same baseband version. We have seen similar products in the past (DROID 2 and DROID R2D2), but they all carried slightly different software versions to accommodate various changes. With the DROID RAZR and DROID RAZR MAXX however, it looks like everything is interchangeable, so savvy users already have a wide range custom ROMs to choose from.
