iSyncr user Timothy Dobbins emailed us (with these screenshots!) to let us know how you connect the HTC One X to your computer.


By default, the phone will be in charge only mode. When it is in the mode, you won't see your phone in iSyncr's menu. (Shown above)
Once you know this, just select "Disk Drive". (Shown Above)


 Then your HTC One X will show up in iSyncr's menu and you can sync away!

Thanks for the info Tim! Hopefully this will save other users a few minutes of head scratching.
