Does cricket require a change in apn settings for iphone 4?

I've done a lot of research but please correct me if i'm wrong. I have recently bought an Iphone 4 off CL, and i'm trying to get onto straight talk. People are telling me that with straight talk you are able to talk and text all you want, but there's no data (since it is an Iphone) I have also heard that if you jailbreak your iphone and change the APN settings you can get the data working. But i have also heard about this "cricket" prepaid service, claiming they are the only ones that carry prepaid iphones. Are these Iphones they sell different from others or can i use cricket on an AT&T Iphone? If i can use an AT&T phone with cricket do i still have to change my APN settings? Please help! I'm supposed to meet a guy at 10:30 tonight to buy another Iphone for my mom, but i don't want to if i wasted my money on mine.

In a T-Mobile 2year contract, can you end it in the middle of the contract?

Recently someone tried to break into my home, and while I was trying to call 911, my Samsung Galaxy S refused to send calls. Instead they went directly to "Call Ended." As I tried to text my mother to alert her she needed to call 911, my phone's keyboard went spontaneously into Japanese letters, meaning all communication was lost. Luckily I'm okay and I managed to reach 911, but seeing how unreliable my phone is and how it could have costed me my life, I'm hoping to break contract with T-Mobile and get an iPhone with a different company. Is it possible to end the contract? If not, would I be able to tell T-Mobile why I want to end and since it is so serious, they would let me end or give me money to upgrade to a better phone?

Is 200 MB of 3G/4G on my iPhone enough for 13 days on T-Mobile?

T-Mobile has a pay by the day option for $3/day unlimited text, calls, and data. The first 200 mb of data are 4G/3G and then after that it's 2G. I want to be able to occasionally check my email, use maps when I get horribly lost, and maybe check facebook when i'm away from Wi-Fi. Is 200 mb will be enough for just 13 days? Or will I eventually be only able to use 2G?
