I'm pretty unhappy with iBlacklist. I purchased it and used it on my 3G for a long time and it worked great. Now they wont let me transfer my purchase to my new iPhone 4. I e-mailed them and they basically told me i have to buy it again! For $12 i should be able to transfer it to my new phone. That is the most expensive app i have ever bought, now I'm gonna have to find a keygen. It's not stealing if I already paid for it legit.
