Whatsapp Jailbreak help!

Oct 25, 2009
I recently brought a new iphone 6 with firmware ios 8.3 and plan to switch over to this new phone from my iphone 5

I had some bad experience when it comes to phones so I did some googling before I start moving stuff over to the new phone

I was planning to jailbreak my phone but then I found that whatsapp can detect jailbroken device and prevent them from verifying, is this possible? And also, do I need to verify my whatsapp number again (same as old phone) on the new phone?
