Problem parse integer within JSON response

[erritikamathur]

I have following JSON response string

{"firstname":"a","lastname":"a","jobtitle":"software developer","companyname":"abc","mobileno":9461438988}

i cant get the string value for 'mobileno' field
This is how i read the 'mobileno' field

self.dispPhone = [NSString stringWithFormat:@"%@ ",[parsedProfileData valueForKey:@"mobileno"]];

the string here becomes some garbage value '2147483647' when i NSLog it
