Is there any way to determine what sites a particular app is trying to reach on startup? Recently took my iPad 1 from 4.3.3 to 5.1.1 and re-jailbroke it on a clean restore, no backups. Overall, it's running well. But I ran into an interesting problem today that has me stumped. One game that pushes this elderly device to its memory limits started crashing at the end of its startup after I installed the same ad-blocking hosts file that's running fine on my iPhone 5. Put the old file back, game loads fully. The weird thing is, the same game loads fine on the iPhone with the exact same hosts file--and the game has no ads. Crash Reporter shows absolutely nothing. It isn't catching these crashes. And before anyone asks--nothing cracked, no sketchy repos, etc. I really want to use the altered hosts file, as the iPad 1 runs much more smoothly without the ads, ESPECIALLY Safari. But with literally hundreds of sites on that blacklist, I honestly have no idea what is keeping this app from opening. Is there any way to see what site(s) the app might be trying to reach? (And why would this be a problem on one device, but not the other? Device speed/RAM? 5.1.1 versus 6.1?) ANY ideas are welcome. It's definitely related to the hosts file somehow--tested Mobile Substrate add-ons & tried the app in Safe Mode with no change. Renamed the new hosts file & put the old one back, it magically works again.
