I hope someone can help me, I cannot find this answer anywhere, I have emailed the creators of iBlacklist but I have not heard back yet. I purchased the full version of iBlacklist. Here is what I have: iPhone 4 Running Version 4.1 (8B117) Firmware 02.10.04 It was jailbroken using Greenp0sion. At first, iBlacklist just was not blocking any of the numbers I had in there & the profile was enabled & the numbers were on the list, i used them out of my contacts, and those are from what I saved when I received calls from them. So I know I am not entering them wrong. Now when I launch the application it shows the iBlacklist home screen, when I click on blacklist or whitelist, it crashes & goes back to the homepage, so I cannot even change any settings to fiddle with it. Please advise on how I can fix this & what I need to do. Thank you. It has me ripping my hair out. lol I had the cracker version of this from the Repo source but it never worked for me either. So this time I uninstalled that one, rebooted my phone, installed the one from BigBoss & purchased the key online.
