I currently have a Iphone 4 with AT&T jailbreak in a 3 lines family plan, I only use one of the lines. My main line is currently eligible for full upgrade and the other two will be eligible May and June 2012. I'm not sure if I should get the new Iphone 4S, I love the iphone but I was really looking forward for a new redesigned iphone 5. I do need to use tethering, my Iphone is jailbreak so i use MYWI to tether the internet to my IPAD2, so if i get the new one i might not be able to tether until hackers/developers release a jailbreak for iphone 4s. I also would want to cancel my other 2 lines or maybe get 2 more Iphones and sell them to be able to pay for the AT&T cancellation fees. Also I get a 20% service discount with Sprint and AT&T thru my employer and right now I only get a 10% discount with AT&T. So I might also consider swapping carriers. please let me know what do you think I should do.
