Hello people of the iphone world. After trying to upgrade my Iphone 4 from 4.00 to 4.1 several times I have finally manged to make it a few days ago using greenPoison RC4. The first attempts sucked - no Facetime, no 3g data, no GPS and more bad things. Now currently everything is working fine and then comes this new Pwnage tool...? Can someone please tell me the difference between upgrading using the "no baseband upgrade with tinyUmbrella" VS this new Pwnage tool? Should I use it? what are the benefits? I'm not that smart about it and english is not my native language so please if possible make it simple. thank you.
