Having major frustrating problems trying to install certain applications. Am convinced something must be wrong with the set-up of my phone - can anyone advise? Both Cab4me and Spotify are listed in the market but will never install. Every single time I try I get 'Download unsuccessful'. When I try to buy RepliGo Reader, I get the message 'There was a problem processing your request. Please visit checkout.google.com to fix it'. BUT I can buy other apps and there's nothing wrong with my Google Checkout. And I can install most other applications. My phone is a HTC Magic on Vodafone in the UK - however it's a replacement handset, and I'm wondering if Vodafone have sent me a phone that's not meant for sale or something and that's why certain apps are blocked?
