setCookie not working for tests run on Iphone agent

Noticed the setCookie method not working for tests triggered on iphone agent using any browser like chrome , firefox…etc.

i have tried by setting following iphone user agents too, but doesn’t seems to be working.

{setUserAgent:‘Mozilla/5.0 (iPhone; CPU iPhone OS 6_0 like Mac OS X) AppleWebKit/536.26 (KHTML, like Gecko) Version/6.0 Mobile/10A5376e Safari/8536.25’},

{setUserAgent: [config.homepage,‘Mozilla/5.0 (iPhone; U; CPU like Mac OS X; en) AppleWebKit/420+ (KHTML, like Gecko) Version/3.0 Mobile/1A543 Safari/419.3’]},

Following is the location used in test script

location: ‘Dulles:Chrome.3GSlow’

Can some one help here?

Test Script:-

{setCookie: [config.homepage,‘SENV=prodb’]},
{setCookie: [config.homepage,‘searchEnv=app-search.’+lowerenv+‘.electrode-search.polaris.glb.prod.walmart.com’]},
