What begs a question, how can cellular phone providers even think, that their team of 12 underpaid code monkeys capable of producing software that's on par with google? AT&T places, map searching apps, etc are utter crap and you can't even get rid of them unless you flash the OS.
Unfortunately this problem isn't tied only to cellular phone providers. Network card manufacturers for Windows (yes, I'm looking at you Intel) come with their own crapware utilities who think their monitoring app is better than default windows wifi manager. Similarly, consumer routers that race to offer more and more features DMZ, QoS, etc but have millions of bugs because they're not software shops and still refuse to use DD-WRT or Open-WRT which are clearly better and have been developed, used and supported by thousands of professional.
