There’s a muttering on the technology blogs about T-Mobile’s decision to block third-party applications from accessing the internet on its handsets, starting from this post on GearLog. “This means T-Mobile feature phone users are prohibited from surfing the Web with Opera Mini, checking maps on Google Local for Mobile, listening to podcasts with Mobilcast, and using any other form of software not pre-approved by T-Mobile.” I’m not sure exactly how new this policy is, but it isn’t popular. And as GearLog points out, its perverse because using 3rd party applications on the handset will increase the amount of data used, raising profits for T-Mobile.
