Cincinnati Bell, a local US service provider, has released a Froyo update that can only be considered “officially unofficial.” See, while Motorola cannot support the release, as they have not actually approved it, Cincinnati Bell has compiled a 22-page upgrade guide, to get you there the hacker way.
The company has compiled the upgrade in a nice .exe file, complete with a friendly big-button UI and nice combination how-to video/PDF combination. While most seasoned Android users will have no problem with the procedure, the average user might run into some problems with the comprehensive instructions, which involves installing Motorola drivers, rooting the device with SuperOneClick, backing up apps via Titanium Backup, installing a custom recovery and flashing the firmware, rooting again, reinstalling missing apps and, finally, unrooting the device.
What is particularly interesting about the upgrade is this is likely the first provider-endorsed unofficial upgrade, likely necessitated by the fact that Motorola has long-ago given up on the XT720. Froyo brings with it portable WiFi hotspot, Flash support, and a host of other performance improvements, so it’s no surprise Cincinnati Bell wanted to go ahead with the upgrade for its customers.
This procedure should work on Wind’s XT720, but obviously the provider will provide no support for the upgrade unless they decide to follow suit. The question is, have you already upgraded your XT720, or will this guide spur you to take the plunge?
