ILR Eligibility : Tier 2 (ICT) + Tier 1 General

Hi,
I have Tier 2(ICT) visa stamped on 2nd March 2010 but i entered into UK on 2nd May.
I got Tier 1(general) visa on 23rd February 2011.

From when would i become eligible to apply for ILR.
Would my Tier 2 visa be counted in for ilr eligibility as i entered into uk after 6th April 2010, but my visa is stamped before april 6th 2010.

Could you please clarify..

Thanks in advance..

You are OK as long as entry clearance was within 90 days and absences are < 180 days per yr

Thanks Argus,
And from when on would i become eligible to apply for?
2nd of Feb or from 3rd of march?

28 days before your current visa expiry

Thanks again Argus..
