I tried to jailbreak my iPhone 4 with 4.0.2 and 1.59.0 but each time I get the message Retry Hold Home and Power. I think it has to do with the fact that iTunes starts each time saying that it detected an iPhone in Recovery mode. Any idea what I can do? Thanks

Tried limera1n against 3GS 4.0.2 new bootrom 5.13.04 baseband. Appeared to work fine but after boot the limera1n icon did not show. Tried many times to no avail. I finally did a factory reset (erased all data/settings) from the phone and after boot the limera1n icon showed up. Just wanted to point this out just in case anyone is running into same problem

I tried on 3gs 4.0.2 5.13 couple of times on PC but the Limera1n would not install on the phone, then factory reset the phone and ran Limera1n and was successfull, now downloading Cydia. Excellent utility, keep it up.
