This one comes as a bit of a surprise. At the Open Mobile Summit conference, Android co-founder and Google Ventures General Partner, Rich Miner said that carriers should put more effort into creating specially tailored interfaces for Android smartphones.
Miner is actually surprised that carriers such as Verizon and AT&T have not put money and time into it already. He points out that Android is open and literally anyone can modify it as much as they like. While this is perfectly and absolutely true, it does not mean that carriers should.
Carriers have long bundled their own applications such as music stores, to check usage allowances and also modified the splash screen. However, further customisation will very easily turn one month software update approval cycles into four months development and approval cycles. As it is, we already wait too long for the latest version of Android and that is bound to offer a lot more than a (probably mediocre) carrier customised interface.
KitGuru says: Stick with the splash screens and a couple of internet bookmarks thank you carriers.
