I have a sprint iphone 5 anyway to jailbreak and use tmobile or straight talk?

Ok so i asked this before but maybe confused people because didn't really get a response to this question. Anyways i have a sprint iphone 5 and not ina good standing acct with sprint due to someone abusing the data and yes that can happen lol
But anyways i literally just got this iphone 5 from them about a month ago and at this point would just like to unlock it. It's my understanding from searching that am iphone 5 is locked to sprint even with an unlock ticket with them it's only unlocked for international use of a gsm sim unlock the verizon version. So my question is has anyone jailbroken the sprint iphone 5 and used it for tmobile or straight talk? Or does anyone know if it's possible? And if so is LTE usable? I figured they may be a tweak or app in cydia since there's a sim card slot. So if anyone could please give some advise it would be greatly appreciated.

I don't think you can use your iPhone on tmobile or straight talk. Both of these phone company's are gsm(use SIM cards) and sprint is cdma(no SIM card). I have my iPhone running on straight talk and they require you have their sims.

The sprint version can only be unlocked for international gsm at the moment. Your best bet is to sell it and get an AT&T or Verizon version. The Verizon version will work right out of the box. The AT&T version would have to be unlocked but it is under $20.00 to do that with about a 24 hour turnaround from a few vendors on the Internet and eBay. The advantage with getting the AT&T version is that it will support TMobile's upcoming LTE on aws band while the Verizon version does not support it. On both you will get HSPA+ 42 network where tmobile has deployed 1900mhz. A lot of major cities have that or are getting it so your best bet is probably AT&T iphone 5 for present and future compatibility.

  • Will a straight talk iPhone work on Tmobile? I want to buy a new one from Walmart but want to keep my Tmobile Plan and not go to Straight Talk, will it work if I insert my sim?
  • What happens If I jailbreak and iphone3GS to straight talk network? Will I be able to use the iPhone apps? Or how does it work? Because if I can use the apps I will most definitely get this done because straight talk is a billion times cheaper.
  • Sprint iPhone 4S, can I use on straight talk? I just bought a sprint iPhone 4S, I called straight talk and asked if it would work if I got a straight talk micro SIM card and if I would get service everywhere I do now with my AT&T android, her answer was yes it would definitely work. I've seen a million different answers on google tho. Has anyone tried this or is doing it now? Please give me and answer and explanation. Thank you!(: The iPhone I bought today HAS A MICRO SIM CARD SLOT.
  • Jailbroken sprint iphone 5 on tmobile or straight talk? I know the sprint phone 5 is locked to only sprint or international gsm use. But what if its jailbroken is there some app or tweak in cydia? I had the iphone 4s jailbroken but converted to android. I would really love the iphone 5 on prepaid so any help would be great.
