So I just got off the phone with Michael from iFixDirect about my prox sensor issue.
For those of you just tuning in.. I ordered the DIY kit and made the swap last week. All went well with the exception of the prox sensor not working.
After trying a few suggestions here I finally gave up and put the black face back on and shipped the whole thing to them overnight.
So we talk and it turns out there is a very good chance my Jailbreak is why my phone doesn't want to work with the new faceplate. My white faceplate works fine on another phone running 4.1. He also mentioned there is another phone in his shop with the same issue, which is also JB.
We all know Apple claimed to make some improvements to the Prox sensor software in 4.1. It would appear these faceplates for whatever reason seem to be dialed into the newest update.
I gave him permission to wipe my phone and upgrade to 4.1 and everything works as advertised. I also had him do the white dock and headphone jack. Figured why not if it was already torn down.
Big props to Michael for figuring this out. He is going to send out an update to his clients letting them know there is a chance the faceplate will not work with pre 4.1 software.
Now. Have they JB 4.1 yet??
Go figure
good customer service, they get a thumbs up from me.
