The free version of the Mantis Bible program for iPhone/iPod Touch has been updated finally to 4.6. It is a bug/performance fix. For me it solves a problem I was having where right after opening the app it was not responsive for a few seconds up to 30 seconds. Haven’t played  with it much, but seems to be a good update.  You can get it in the iTunes App store. And as always, if you have it installed open the App store on the device and it will show the availability of it.
