4.3.3 has had a jailbreak and unlock (I believe) option for some time. 4.3.3 and 4.2.10 are not equivalent software versions, either. 4.3.5 is the GSM equivalent to the CDMA 4.2.10
You can jailbreak using sn0wbreeze or redsn0w but unless you have a gevey sim you can't unlock. Unless you were smart enough to preserve your baseband from a year ago. I assume this is iPhone 4.
yes its a iphone 4 4.3.3 and base 4.10 I was aware you could jailbreak the 4.3.3 just was not sure if there was an un lock available yet for the 4.10 . thanks
