Update Firmware For LG Optimus 7 On Any Carrier


Unlike Android, Windows Phone 7 does not have a lot of flavours and supporting devices, owing to the fact that the platform is pretty new and is still in early stages of maturity. However, that does not mean that it’s the same for every mobile device. There are a few little variations in WP7 for every device, and that is why all carriers and OEMs have their own firmware versions. If you are an LG Optimus 7 owner, you must have noticed that some of the options are carrier specific in your phone and are quite different as compared to other WP7 devices. You can change that by de-branding your phone, but that will give you a device without any associated carrier. Ever wondered if you can switch to any particular carrier? This is possible, and here’s how you can do this.
