Replaced iPhone 3GS's Digitizer and Frame, now white screen?

I have a white iPhone 3GS, as you probably know the white version only comes with a white back, and the screen is still black, so I decided to buy a new digitizer off ebay to make my phone completely white.

The repair was successful, my phone worked, but I realised my screen was at a slight angle because I didn't place it in probably, so I turned my phone off, got the suction cup, and took off the screen, I tugged a little to hard to the cables came out too, so I put them back in and re-positioned the screen.

I then pressed the power button, and nothing happened, but it was turning on, when it finishes booting up a white screen appears, I can toggle this on and off by pressing the lock button.

My phone shows no image when booting up, doesn't even turn on, just stays off until it's completely loaded.

The phone still works, I can use voice control, and I can still power off, etc, but I just can't see anything on the screen.

I have tried plugging in the screen again and the cables are in fine, the digitizer still works because I can hear the sound it makes when I press on it to enter my passcode.

I have also tried holding the home and lock button at the same time, but my finger keeps slipping after a few minutes, but I don't think that would solve the issue.

What are your suggestions?

IPhone freezes then restarts itself?

Okay this is weird. My iPhone 4 recently started spazzing out on me.

I think it might have something to do with storage space, since it started shortly after I got a message about my storage space being low. But when I slide the bar across to unlock my phone, about half the time he screen will freeze, then it'll take about 3-5 minutes for it to restart itself

I'm running 5.1.1 if it matters.

FedEx delivery tracking - how soon does it show up online?

I have an iPhone 5 being delivered today and FedEx is going to leave it on my doorstep. When I check the FedEx tracking it shows at 6:52am it is "On FedEx vehicle for delivery". If they actually drop it off at my house at say for example 9:52am, how soon after that will it show online that it has been dropped off? Will it show up at 9:53am online that says it was dropped off at 9:52am? I'm working, but as soon as it gets delivered, I can go home quickly and get it.

I brought my iphone 4 on ebay recently, can I still get insurance?

I'm struggling to find insurance for my new (second-hand) iphone which my sister bought for me on ebay. I technically have proof of purchase but don't know how old it is and many places don't insure phones brought through online auction.

Can anyone suggest an insurer that will insure regardless of age/method of purchase?
