1) Does anyone know if the update still works? I did tried it today but didn't get too far. On the LGMobile Support Tool it says Model: GW620R Version: V10C Everything looks good so far but when it gets to the ANALYSIS part, I have to close it because it says "Software update is not supported for this model" Help? 2) For people who did the firmware update, do your text messages get deleted? I'm quite a newbie so sorry if this is a stupid question! 3) Since my text messages could potentially be deleted, how do I back them up or save them to my sim card?
