According to T-Mobile’s official Twitter account, the GPS fix being handed down through Kies for Samsung Vibrant owners (reported last night here) is to be avoided. To quote the tweet:
@jammallnyte73 An OTA update will be announced soon. Please do not install the kies update due to some known issues.
This tweet was a response to the user mentioned when he asked why the update through Kies for his Vibrant wasn’t showing up.
Keep you eyes here for more info, and we’ll let you know as soon as we do about T-Mobile’s OTA update. Looks like someone should be doing some more testing before rolling out their updates!
