With Symbian regarded as dead in the US, T-Mobile is said to have no plan on updating the Astound, their C7 variant, to Belle.

Nokia have revealed that T-Mobile will not be updating the Astound past Anna. Users who have imported their C7s will be able to update and users will probably be able to use Navifirm to flash it onto their devices, but the official channels are closed. Belle is said to bring significant speed and UI improvements, an ideal upgrade for any Symbian users, but guess we’ll have to see about that.
