What other carriers work with a factory unlocked iPhone 4? - 1

I'm thinking of buying a used factory unlocked iPhone 4 from ebay. I do not want to use Verizon, AT&T, or Sprint because they charge a high monthly fee. I would like to use another carrier. I need to know the specific names of other carriers that would support its signal. I can't seem to find this information. Also don't tell me the answer like "All CDMA, GSM carriers, etc" I need to know specific names of carriers.

How to activate an iPhone 4 without a Sim Card?

**My sim card reader is broken.
*** Phone's trapped on the grey "Insert Valid Sim to Activate" screen
***I'm currently on iOS 6.1, Baseband 4.12.05

I can't use the phone, as a phone. But it would still be ok for pics, storage, iPod, etc.
So what I must do is Hacktivate the iPhone, or throw it away.

As with older methods of Hacktivation, I've tried jailbreaking first.
I've tried jailbreaking it with Evasi0n, and redsn0w. The device has to be already activated to be jailbroken currently with iOS 6.1. Even with the phone in Restore/DFU mode, the jailbreak software detects the phone has not been activated. RedSnow doesn't currently support iOS-6.1 anyway.

The sim reader is attached to the main board, so it's pretty much impossible for me to repair. (I'm not interested in paying for repair either)

**ALSO*** I have another phone on iOS-6.1, baseband 4.12.05.It has been locked by AT&T because it was lost, eventually it was found. When an unlock comes out for iOS-6.1 will this phone be usable on another network? Like tmobile. Or is it now permanently an iPod?

I know when a phone is lost, or contract unpaid on Sprint. Sprint/Verizon locks the ESN, but once the phone is properly unlocked from the sprint network it can be used on verizon no prob. There's a bunch like that for sale on eBay everyday.

My iPhone's iMessage isn't working properly

Hi! I'm having a real issue with my iPhone and iMessage. For a VERY long time, my mom and I have both owned and used iPhones, and, consequently, iMessage. Well, recently she betrayed Apple and switched to Android (gasp!). Well, since then, I can't send ANY texts to her! This is because my iPhone (4S) won't detect that it is an Android, and I have to manually send each iMessage text as a regular text message. It's a real nuisance, and I was wondering if there was any way to fix this?

I made sure her contact is no longer associated with "iPhone" contact and her number is listed as "Mobile" instead of "iPhone". And when THAT didn't work, I created a new contact completely, but it STILL recognizes her number as an iPhone number! Please help me if you can!

Added (1). My Mom currently has an HTC DROID DNA and I have an iPhone 4S.

IPhone screen shattered, is it replaceable?

So I left my phone on top of my car this morning and I forgot all about it… It fell off in the middle of the road and got ran over by another car. The screen is pretty bad, but my phone still works. I still get calls and texts, but I can't unlock my phone because my touch screen won't work. If the screen is cracked so bad that the touch screen won't even work, will getting my screen replaced work? Or am I gonna need to just get another phone?
