So after about a little over 1 hour, (kept taking breaks due to my neck hurting), I finally finished the white swap from Zeetron. This process is very tedious as there are so many small and fragile parts in the phone. On a scale of 1-10 for difficulty, I give it about a 7. It's not hard when you know what you're doing, it's just very time consuming and nerve-racking. I could see myself doing this again if I had to for warranty purposes, or if I got paid for it.
I reused the grill from my original black for the ear piece, proximity sensor works, home button works, everything is working as it's supposed to. I notice though on the backplate, the writing is crooked. I don't plan on using it as I already have one from iResQ and it looks great. So that seems to be the only flaw.
Another thing that I'm noticing is that in the top middle of my screen, there seems to be a 'warm'/yellow spot whenever there are bright colors within the open pages/apps. Not to big of a deal for me since it doesn't bother me too much.
One thing about Zeetron though is that they didn't ship my package until 2 days after my order was processed, even though I paid for 2nd day shipping. So I'm currently emailing them back and forth to see if they will refund my shipping as I didn't get my package until 6 days later (5 working days).
Overall, if you really want a White iPhone 4, the swap process is pretty manageable and great looking. Just look and price different companies if you plan to do it yourself, or send your phone off to someone who does it for you. I don't mean to jack this thread, but I didn't think a new one was necessary, so I'm willing to answer any and all questions for you! Thanks for reading.
