|I know you're waiting for the update - and I'm working on it 24/7.|
Unfortunately there were a few problems - some performance issues on older devices and some random crashes - that need to be addressed.
iPad 2 owners maybe won't care, but since F-SIM used to work well even on 2nd generation iPhones and iPod touch, I think that users of these devices would expect that the update doesn't decrease the performance. And of course nobody likes apps that crash.
This triggered a major rewrite of the rendering code, which is almost finished now. My apologies for the delay, but bear with me, the update will be great!
