hello, i use my phone as a pager to alert me of work-related emergencies/urgent situations. as such, i set it up to make sound (not DND mode) but only for phone calls and pages. with the ios7 update, i have found that the sound which it makes when you make an app store purchase on another device cannot be configured or disabled. can someone please confirm or deny that this is the case - that there is no way to keep your phone from making noise when a purchase is made without silencing all sound? i looked for this setting in notification settings, sound settings, and itunes/app store settings, to no avail. thank you for your time.
