Unlock 3.10.01 Baseband on iPhone 4 Running iOS 4.2.1 on Progress

Couple of days ago, we reported you about the capability of downgrading iPhone 4 baseband 2.10.04 to 1.59.00 which can be unlocked with ultrasn0w, which may be perfect solution to unlock iPhone 4.
Few minutes ago, Sherif Hashim the well-known iPhone hacker has replied someone via his twitter account confirming that work on 3.10.01 baseband is in progress.

Prostat_Pukis asking: that unlock will be for BB 03.10 as well?
sherif_hashim replying: yes

Don't ask about the timing as till now there's now estimate to arrival, but my own expectations that we will see something by the Xmas, stay tuned.
