sara silverman, people tookfun.st couple years and the great success you've had. the way you sort of say at&t is focused on other things. perhaps a fair point, but they've noticed and they've got, you know, the ability to compete on price. they're reprising their entire subscriber base to a certain extent, even verizon, gotten their attention as well. marchelo at sprint is a big guy and he's getting more competitive as he fixes his network and tries to come in with competitive prices. churn is going up. i wonder whether it can be as easy as it's been the last couple years when nobody expected much from you. >> doesn't that sound like the exact xfrgs we had one year ago, at&t and verizon will respond, sprint will it fix their network and come back at you. it's 2015. at&t and verizon did try to come back, margins were down, churn was up 14 and 23% in q4. ours was up seasonally 5%. >> your guidance some people are pointing to on sub ads seems somewhat modest. >> we announced post-paid ads of 2.2 to 3.2. we did 4.9 last
