How to fix some mysterious problems.

I've tried to jailbreak a locked SIM-less (no sim card) iphone 4 .. attempted 3 times and in the forth it seemed to be successful but when rebooted the skull logo was not there. Before rebooting i checked for loader or cydia but nothing.

My question is, can I jailbreak a locked SIM-less iDevice? If not then what tools should i use to unlock the idevice then jailbreak it?

The problem maybe the firmware version of the iphone, GP only works on 4.2.1, I've jailbroken enuff carrier locked iphones with GP with the sim out so it does work. Iguess if you have no springboard to check firmware you could try using TinyUmbrella and see if it recognises the iphone (no need to be jailbroken for this), if so it will tell you firmware & baseband version under the 'general' tab.

Sorry I forgot to mention it's 4.1 & I used GP rc4 for 2 or 3 attempts

Well there you go then, that would be a starting point, as already stated by me and a requirement in the read me(unless verizon), you need to be on 4.2.1 , but be aware of your baseband needs before considering going to stock 4.2.1

but the RC4 should work on the 4.1 right?

Ok, yes my bad, rc4 should work on 4.1, I had to dig in the memory then coz it was gonna be GP with the shatter exploit, but Geohot released limera1n and caused a bit of a stir, but his exploit was used by a delayed GP in the end, maybe you can try limera1n for your jailbreak.
