I bought my One X one release-day and within 2 weeks the update search stopped confirming whether it was actually updating or not. It also stopped restricting me to 1 search per day. After speaking with ATT and HTC, it seems that there is an available update but my phone is not actually searching for "on-air" updates anymore and that I will have to do it manually online, which deletes all personal info from the phone. This is beyond aggravating for me as I use the phone heavily for business and don't want to deal with a system reset.
Anyone else run into this and have a solution? Also, if you are in the US and haven't received an update, you may be in the same boat as me.
