How to bypass Whatsapp Verification Code?

I'm an international student studying abroad in Chile, and have an iPhone 4 (not the s). My service provider (Sprint) suspended my service while I'm here, as it is impossible anyways for my phone to receive service from the US (I have already tried asking them to turn it on for a day), therefore it is impossible for me to receive an SMS message with the verification code from whatsapp in order to activate my number. I have read there are ways to intercept this code before it is sent to whatsapp from my phone. Is there any way anyone can post detailed instructions on how to do this? Are there other methods?

I have read that you can possibly jailbreak your iphone and possibly unlock it. Does anyone know if Sprint Iphone 4's are capable of being unlocked as well?

What is the best possible option for me in this scenario? Thank you so much. Besides email this is the only method I have of talking to my mom at home, and she is super worried that I can't use Whatsapp now.

Thanks!

Added (1). -Edit: I know about skype, facebook, viber etc, but whatsapp is the most convenient and most chileans here use this app. So in the long run this saves me a lot of money in buy prepaid texting. My main question is about whatsapp.

Can't move songs from iTunes to iPhone? NO NEW LAPTOP OR PHONE?

I haven't got a new laptop or a new phone or updated anything. Yesterday I opened my iTunes to find all my music gone, it was still in my files so I was able to copy it across again. Since then I have been unable to copy any music over to my phone. When I press 'sync' it just doesn't add anything new, and if I try to drag items across individually I just get a little red circle with a line through it.

Don't really understand what's happening as I haven't had any updates or anything. I literally haven't changed a thing, it's just started doing this for no apparent reason. As I'm sure you can understand, this is one of the worst things that can happen to a person. I would be infinitely in debt to anybody who can solve my problem.

Gumtree Australia: how to tell if a seller is trustworthy?

I found an ad for a near new iphone 4s 64g selling for $150. The description within the add seems reliable but i'm aware that $150 for a new iphone 4s 64g is ridiculously cheap so i'm wondering if there's any tips to tell if the seller is trustworthy? What types of questions to ask? And is there any insurance policy that protects buyers from scamming on gumtree?

My Iphone 5 charger won't work? - 1

I've had 4 iphone 5 chargers.
-First one in which broken randomly, withihn its use it always said, "charging not available with this accessory." It came with it. Of course it was all twisted and stuff at the end from me trying the get it to charge.
-Second one i bought from best buy, it was all fine until one day when i layed it down, it beeped indicating it wasn't charging, so i positioned it, and it did the same thing the first did, until i had it all twister also.
-The third i got from the gas station. It ripped.__.
-Fourth i recently got from the gas station, it just stopped working today.
I'm UTTERLY FRUSTRATED! My iphone works fine so no android fanboys please. But i do believe there's either a problem with the phone charging, i'm doing something wrong, or my battery (inside the iphone) is damaged. What do you think? Should I proceed in buying a whole new phone over this or fixed the damaged battery, & if so, where?

Fun strategy/RPG/adventure/tower defense games for iPad/iPhone?

Pretty much been searching for a new app to play. I've played things like bloons td5, clash of clans, battleheart, infinity blade, cartoon wars, plague inc… But i'm really bored of them now.

I'm looking for a good app that lasts quite a bit and doesn't have all the gay 'buy in game' *** that ruins it. Been searching for a while and can't find anything worthy of spending $ on. Any suggestions?

My iPhone 4S won't let me download free apps

My App Store worked for a while. I've had this phone for almost a month, and since last week every time I try to download a free app, it will tell me that I have a billing issue.
I shouldn't have a billing issue if I'm downloading a FREE app. Please help me.

*i have money on my card, so there shouldn't be a billing issue.*
