End of my tether (no pun intended)

[Scarthhd]

Have tried different ways to jailbreak and upgrade the baseband on my wives baseband to iPad baseband,

I have an iPhone 3GS on firmware 4.3.5 and its currently set to O2 I knw the ultra and Cheka, I just need a sure fire way this will work, I either get the iTunes logo the pineapple or the apple logo, and it won't kick out of recovery,

Please some help,
