Can iPhone hardware defects affect performance of some apps?

I recently have had to get an iPhone 4 repaired. My LCD screen was not lighting up and not even a system restore could change that. I took it to a center and while they did manage to fix it, now I'm having trouble with some apps, namely Twitter and Facebook. Just those two go into like a small-screen glitch when I try to load them. My assistive touch doesn't work anymore either; it just sits in the center of the screen, unresponsive.

I understand this problem isn't very common, so if you know of anything I could do to get everything functional again, I could use the help.

Can my locked AT&T Note 2 be used on Straight Talk?

I recently purchased a used AT&T Samsung Galaxy Note 2 from a company who sells used/refurbished phones named Digicircle. The phone is in mint condition and has a clean ESN/IMEI however it is locked to AT&T. I'm a customer of Straight Talk (ST) and my AT&T compatible ST sim card is not working in the AT&T phone. However, I thought it would automatically work when I inserted the sim card but instead a "no service" sign shows up at the top and sometimes the service will come in but majority of the time it has the "no service" sign. So I assumed that the phone had an antenna problem as the sim works when I plug it into my AT&T iPhone 4. I called ST and they told me that the phone must be unlocked. The only problem is that AT&T won't do it unless I have the information of the individual who had the phone with AT&T to unlock it. But there's no way I could get a hold of that info out as the individual sold it to the company and the company sold it to me. Can ANYONE help me? I know unlocking phones are illegal now… What should I do? I need help As soon as possible
