Hey guys, there's a lot more into that. We had setbacks with our code base, and a bit of complications here & there that we're trying to resolve thus our frustration. Based on our code base and the performance of the current app(we have been criticized for the performance on a few occasions including reviews of Nokia Lumia 900 and HTC Titan 2 both on The Verge website and we really need to step it up and produce a better performing app.
With WP8 days approaching it would be a better decision to start over with WP8 and Win8 since the team has changed too.
We're still looking at ways that we could tackle this. We should have something to announce in a bit.
If you pull the app from WP7 Carbon is officially dead for me.
Seriously - you have been promising an update for ages. Still waiting for it.
Meanwhile rowi, mehdoh and even twabbit have surpassed Carbon in terms of usability and speed by FAR.
If they manage to get fast code running you can do it too.
If you decide on dropping WP7.x support I can't be an advocate for CarbonWP any longer. I was really REALLY in favor of your app because of its interface - but dropping the support now because you can't get your code together is just a huge disappointment.
When CarbonWP came out, I gladly paid for your app without even testing it before.
I hope you are happy with that money because you almost fixed NOTHING for that and now you even plan on pulling it altogether.
I, and I'm sure a lot of other users, are not going to fall for that for a second time.
