Motorola reveals what is in store for Motorola DROID RAZR and DROID RAZR MAXX owners with update
Another bug will be fixed with the update and ironically, it too deals with a roaming issue. This bug caused a data roaming warning to appear while connected to an extended network. This means that you are in an area (like Alaska) where Big Red's towers are not reaching you, but the carrier has an arrangement with other operators to provide you service at no extra cost.
The update is coming to both phones OTA and Motorola suggests that you have your phone hooked up to a Wi-Fi connection when downloading it. After all, you need to preserve your precious data allowance. Additionally, your battery should be charged to at least 50%.
